1 GENERAL
The SIG60 is a second generation transceiver for digital communication over battery powerline. It
allows the powerline to be employed for both power and communication, thus eliminating the need for
special wires for carrying control and data. The SIG60 uses a unique multiplex digital signaling
technology that es the powerline noisy environment. A small footprint integrates most of the
external components needed for its operation. A sleep mode puts the device in a power saving mode
while it is still capable of sensing the bus for remote wakeup messages from other devices.
The communication over powerline reduces harness and connector size, increases reliability, saves
node costs and increases the network throughput.
The powerline new physical layer is useful for a wide range of Automotive, Avionics and Industrial
applications. These include sensor readings, actuator activation, doors, seats, mirrors, climate control,
lights, Truck-Trailer, etc. The SIG60 contains a UART host interface, modem, line driver and ceramic
filter interface.
The SIG60 operates as an AC/DC Powerline transceiver that replaces the RS232 / LIN transceivers
thus eliminating the Data wire. Providing up to 115.2 Kbps data rate, the SIG60 offers a significantly
improved data rate as compared to the LIN network. The SIG60 network consists of a Master and
Salves. Each SIG60 device operates also as a Slave in a multiplex network. Multiple networks may
operate concurrently over the same wire by using different carrier frequencies. The SIG60 activates
SIG61 smart powerline slave devices
The SIG60 contains a host UART interface, modem, line driver and interface with two external ceramic
filters (one of them is optional). The device features a unique Signaling technology to e the
hostile communication conditions of a vehicle battery line. Sleep mechanism reduces significantly the
power consumption when in Sleep mode, while sensing periodically the powerline for wakeup
messages from other devices.

2 OVERVIEW
2.1 Signaling System
The SIG60 device is based on a unique Signaling technology. The device transmits and receives a
special signaling carrier, which can be differentiated from the Power line noise. The receiver receives
the signaling patterns at a selected frequency and extracts the data from the noisy channel into the
original bits. Multiple devices can be used as a network on any of the available carrier frequencies.
Multiple channels can operate over the same Powerline noisy lines for additional independent networks.
2.2 Channels and Network
The SIG60-SIG61 network can be set into 16 groups of frequency pairs. When set to such a pair, its two
preset frequencies can be easily switched.
Each channel can broadcast asynchronous data messages to other devices on the Power line. The
device allows the use of the LIN protocol. The SIG60 device is controlled by a host microprocessor
through its UART port.
Channel frequencies: 1.75MHz, 4.5 MHz, 5.5 MHz, 6 MHz, 6.5 MHz, 10.5 MHz and 13MHz.
Data transfer rate: 9.6Kbps to 115.2Kbps.
Cable length: See 3.3.11.
2.3 The SIG60 Device
The SIG60 device is responsible for transferring messages to all devices over the line. The device
handles the communication physical layer and Interference detection. The device communicates with its
host via an asynchronous serial port for data transfer and device control. Figure 2.1 outlines the building
blocks of the SIG60 device.

2.4 Protocol
The SIG60 may be used in a Master-Slaves network using UART based protocols such as the LIN
protocol. The device receives any asynchronous byte (one start and one stop bit), as so, it is
transparent to the host while providing additional services for the link and application layers with a builtin
Interference detector and frequency management.
2.5 Power Management
Sleep Mode, controlled by the host, saves power by disabling most of the SIG60 internal circuits.
During Sleep Mode, the device is switched ON every 32mSec, for a short period to detect wakeup
messages from other devices on the bus. If no activity is detected, the device is switched back to Sleep.

• F0 and F1 are ceramic filters
• Adjust R1 for maximal output level without distortion on powerline.
• C1 and C2 values depend on crystal used. Usually values are between 0pF (NC) to 1.5pF.
• Optional 3MHz HPF for very noisy channels, replace C9 with C9a, C11, D8 and L3
• F1 is an optional communication channel
3.1.1 Ceramic Filter Considerations
The SIG60 is designed to operate with one ceramic filter for transmission and reception. However, if
switching between two channels is desired, two ceramic filters are required. The minimum allowable
bandwidth of the ceramic filters is +/-60 kHz @ 3dB. Narrow bandwidth limits the maximal bit rate.
The SIG60 selectable frequencies meet market available ceramic filters. It is important to select the
widest bandwidth available. 1.75MHz, 10.5MHz and 13MHz may use discrete filters.
Through hole ceramic filters are available from Oscilent.

3.1.2 Communication performance
The maximal cable length between extreme devices depends mainly on the AC impedance of loads
connected to that line and number of nodes. The power cable length has less effect on communication.
The SIG60 needs at least 20mVpp for proper reception. Good communication should be achieved if the
transmitted signal can be seen on an oscilloscope at the receiving side within the line noise.
3.2 Frequency Control
The device is designed for operation in two selectable carrier frequencies.
Presence of an interference signal can be read from the device internal register.
3.2.1 Operating Frequency
Either Bit 0 in control register 0 or input pin F1nF0, determines the operating frequency F1 or F0. The
current operating frequency can be determined by the status of output pin MF1nF0.
3.2.2 Interference Hoping
When InterfHop pin is high, the device switches its channel automatically whenever an interference
signal is detected in the operating frequency. If the device does not receive any data in the new
channel it will return to the previous channel after 2Sec. If, again, no data has been received for 2Sec.
and the interference has stopped, it will switch frequency once more and will stay at the new channel.
3.3 Crystal Oscillator
The SIG60 is designed to operate with a low cost 4MHz crystal connected between OscIn and
OscOut pins.
The values of C1, C2 in Figure 3.3 oscillator circuitry should be determined ording to the crystal
manufacturer mendations. Values of C1, C2 should be between 0pF and 1.5pF

4 OPERATION
4.1 Message Construction
The host constructs a message from bytes of data sent to its UART. The device receives this data on
its HDI data-In line. The 1st low input bit (start bit) starts the signaling transmission, and the 10th high bit
(stop bit) stops the transmission. If all bits, including the 10th bit, are low, the transmission continues
until the HDI es high, but no more than 31-bit duration. It is considered as the Synch_Break Field
of the LIN protocol. The stop bit stops the transmission unless a new byte is received from host. The
data latency between transmitter and receiver is about four bits.
4.1.1 Data bytes
Two kinds of bytes are allowed:
1. Bytes beginning with a start bit, followed by 8 bits and ending with a stop bit.
2. Bytes beginning with a start bit followed by a number of zeros ranging from 9 to 30 bits and
ending with a stop bit (indicating a SIG61 command).
4.1.2 Commanding the SIG60
The SIG60 operation mode can be set by writing and reading to/from the internal Control registers (See
section 4.2). The registers default values at power-up are: Bit-rate = 19.2KBps, F0 = 5.5Mhz and F1 =
6.5Mhz. Writing into the registers allows changing the selectable frequencies, the bit rate and the
operating frequency. It also allows activating the automatic sleep feature and the automatic response to
received bytes feature.
4.1.3 Transmit
Upon detection of a start bit in HDI, the SIG60 starts to transmit modulated signal to the Power line
ording to the set-up channel frequency and bit rate. See figure 4.01 below for Transmit path.
Note: After transmission, it takes the duration of 2 bits before the device starts to listen to the Powerline.
Figure 4.01 – Transmit path.
4.1.4 Receive
When not transmitting, the SIG60 listens to the Power line in order to:
• Detect and decode a legal signaling pattern ording to the setup channel and bit rate.
• In Sleep mode, the device detects wakeup messages.
• Detects Interference signals.
Figure 4.02 describes the receive path.

4.3.1 Command Mode
When in command mode, the host can configure the device ording to the desired operating
parameters. The device enters command mode when pin HDC is lowered to “0”. When in command
mode, data on the HDI pin is not transmitted to the bus, but is used to configure the SIG60. The
command can be written in any of the allowed bit rates.
In order to write to a control register, the host sends two bytes. The first byte begins with the address of
the register followed by 5(hex). The second byte is the configuration data, as shown in figure 4.1. The
bytes should be sent more than 200nSec after lowering HDC.

4.4 Loopback
The device operates like a transceiver, therefore while transmitting or writing a command the HDI signal
is looped back to the HDO pin. This feature can be controlled using Bit 6 in control register 0.
4.5 Reset and Power-up
The device has internal Power-up reset. It takes 6mS until a stable operation is achieved from powerup,
or from raising the nReset signal to high.
4.6 Sleep Mode
The device has three operation modes: Normal mode (normal transmitting and receiving), Sleep mode
(power saving mode), and Standby mode (after waking up, while pin nSleep is low). Transitions
between the modes are done via dedicated pins, or remotely, due to bus activity.
During the Sleep mode, the device enters into power saving operation where only its internal low
frequency clock operates. The device wakeup every 32mS for duration of 1.5mS to detect a dedicated
wakeup message on the bus. If such message is detected, the device switches to Standby mode,
raising its INH pin to wake/indicate its host that a wakeup message detected. It is the responsibility of
the host to raise the Sleep pin in order to switch to Normal operation mode. The Wakeup message is
generated automatically by any device that detects transition from High to Low or vise versa on its
Wake pin. The Wake message duration is ording to bit [3] in control register 0.
4.6.1 Entering Sleep mode
The host can place the device into Sleep mode either by a lowering to "0" (falling edge) pin nSleep or
enabling the AutoSleep option (Clearing bit [4] in control register 0).
When AutoSleep option is enabled the device will enter Sleep mode if there was no bus activity for a
period of 8 Sec. When the device enters to Sleep mode it lowers pin INH.
There are three ways to wakeup the device from Sleep mode.
4.6.2 Wakeup from pin nSleep
In this case, the host raises the nSleep pin. The device then enters Normal mode and raises pin INH.
If the device has entered the Sleep mode due to the AutoSleep function, then the host needs to lower
pin nSleep and raise it back. The device automatically transmits a wakeup message to wakeup all other
devices on the bus. While transmitting this wakeup message to the bus, the device lowers pin HDO.
After the transmission is complete the device raises pin HDO (can be used to signal/interrupt the host).
After the transmission is completed and pin nSleep is high, the device enters Normal mode. See Figure
4.3 for signals description.
Figure 4.3 - Wakeup from nSleep pin
4.6.3 Wakeup from pin Wake
In this case, a transition on pin Wake (can be caused by an external switch of the application) is used to
wake the device. The device then enters Standby mode, raises pin INH, and transmits a wakeup
message to the bus. While transmitting the wakeup message to the bus, the device lowers pin HDO.
After the transmission is complete the device raises pin HDO (can be used to signal/interrupt the host).

and pin nSleep is high, the device enters Normal mode. The host has to raise the nSleep pin (otherwise
the device will remain in Standby mode).
Figure 4.4 - Wakeup from Wake pin
4.6.4 Wakeup from bus message
During Sleep mode, the device wakes up every 32mS periodically to check for activity on the bus. If a
wakeup message is detected, the device enters Standby mode and raises pin INH. The device then
signals the host by lowering pin HDO pin for a minimal duration of 8 bits, and a maximal duration of
about 150mSec. The host has to raise nSleep pin (otherwise the device will remain in Standby mode).
After completing the reception, the device enters Normal mode. See Figure 4.5 for signals description.
