Preliminary Data Sheet
SIG61 - Smart Slave for
Multiplex Powerline Network
This information is preliminary and may be changed without notice
1 GENERAL
The SIG61 is an independent slave in a Powerline communication network controlled by a SIG60
master device. The SIG61 has 4 identification (ID) pins, used to set the device address, 8 input pins
and 8 output pins. The master can access any SIG61 device independently by using the proper device
address. Data received from a remote SIG60 Master device is reflected to its output pins. The Master
device can read the SIG61 input pins remotely. Its small footprint integrates most of the components
needed for proper operation allowing small-size control solutions.
The SIG61 is an economical slave device for applications such as controlling motors, reading sensors
etc., eliminating the need for dedicated control wires and a host controller for its operation. It helps
reducing the harness size and increase reliability. The SIG61 has a sleep mode that enables power
saving; special Wakeup messages on the AC or DC line are used to signal the sleeping devices to
return to normal operation mode.
The SIG61 is useful for a wide range of Automotive, Avionics and Industrial applications such as sensor
reading, actuator activation, doors, seats, mirrors, climate control, lights, Truck-Trailer, etc.

2 OVERVIEW
The SIG61 is an independent slave in a Master-Slaves network operating on a selected narrow band
channel. A single SIG60 master controls all the slaves in a network; the slaves may be SIG61 devices
as well as SIG60 devices operating as slaves.
Proper Network operation is maintained by employing 5 types of command messages: Read, Readchange, Write, Sleep and Change-Frequency. The command format is similar to the standard Universal
Asynchronous Receiver Transmitter (UART).
The SIG61 has internal narrow band modem, capable of operating in noisy environments. The receiver
listens to the Powerline on its preset frequency. It filters out the signal from noise and interference and
tries to recover the original command. If the checksum is correct, the SIG61 extracts the ID, Command
and the Data.
If the received ID matches its own ID, the SIG61 proceeds to detect the received command. When a
Write command is received, the data part of the command is directed to the corresponding 8 output
pins. When a Read command is detected, the SIG61 responds by transmitting a dedicated message
towards the master containing an image of its 8 input pins.
Multiple networks can operate concurrently on the same wire using different carrier frequencies.
2.1
Channels and Network
The SIG60-SIG61 network supports 16 combinations of frequency pairs. When set to such a pair, it is
easy to switch from one frequency to the other when such need arises. Each channel accommodates a
single SIG60 master and up to 15 SIG61/SIG60 slave devices. Additional SIG60-SIG61 networks can
coexist on the same power line by employing different frequencies for each network, thus allowing
different applications.
Channel frequencies: 1.75MHz, 4.5MHz, 5.5MHz, 6.0MHz, 6.5MHz, 10.5MHz and 13.0MHz.
Data transfer rate:
9.6Kbps up to 115.2Kbps.
Cable length: Dependant on external AC loads connected to the AC/DC Powerline.

Description
Control Signals
Digital data output signal. Output the received data from the
powerline to the host.
Inhibit output for enabling the host or an external voltage regulator
powering the host. This signal is HIGH in the normal and standby
modes and LOW in sleep mode.
Sleep control input. Pulling this signal to LOW puts the SIG61 in
sleep mode. Should be pulled to Vdd.
Local wakeup input. Negative or positive edge triggered. This pin can
be connected to an external switch in the application. When the pin is
triggered the device will wake up and send a wake up message to all
the devices on the network. When not in use, this pin should be
pulled Up or Down.
Input, PU Reset Input
Input, PD Allows automatic frequency hoping whenever an interference signal
is detected on the power line. When HIGH, detection of interference
switches the operating frequency between F0 and F1. If at the new
frequency, no reception occurred for 2 sec, the operating frequency is
switched back. For designs with a single channel this pin should be
tied to ground.

Vdd and Gnd layout traces should be as wide as possible. It is recommended to connect a 0.1uF
capacitor between each Vdd and ground pins, as close as possible to the pins.
Analog Vdd pin, AVdd, should be connected to Vdd. AGnd should be connected to ground. The Analog
supply has to be sufficiently powerful (capable of current driving), to avoid any fluctuations of supply
voltage level. It is recommended to keep the lines connecting the 3.3V power supply to Vdd pins as
short as possible with wide PCB traces.

Ceramic Filter Considerations
The SIG61 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 SIG61 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.

Oscillator
The SIG61 is designed to operate with a low cost 4MHz crystal connected between OscIn and
OscOut pins. Each of these pins should be connected to the ground via a capacitor. All the
corresponding PCB traces should be as short as possible.
Recommended crystals are:
1. NDK AT-51 GW.
2. Epson MA-506.
The values of C1, and C2 in Figure 3.3, pertaining to the oscillator circuitry, should be determined
according to the crystal manufacturer recommendations. Values between 0pF and 1.5pF may serve as
good starting point.
The overall frequency tolerance should not exceed 200ppm.
3.4
Communication performance
The maximum cable length between two devices depends mainly on the AC impedance of loads
connected to that line and number of nodes. The Powerline cable length has less effect on
communication. The SIG61 requires a minimum received signal of 20mVpp for proper reception.

DEVICE OPERATION
Protocol
The device operation is controlled via 5 types of commands:
Write command - Upon receiving a Write command with the SIG61 specific ID, the device shall output
the data byte content as indicated by the command to its Output pins.
Read command - Upon receiving a Read massage with the SIG61 specific ID, the device shall
respond by sending a message containing the status of its Input pins (followed by an appropriate
checksum).
Read-Change command - When receiving a Read-Change massage with the SIG61 specific ID, the
device shall respond to the command by indicating if a pulse upon detecting the first change on its input
pins. The response message shall contain the new status of the input pins followed by an appropriate
checksum.
Sleep command - Upon receiving a Sleep command, the device shall enter a low power-consumption
(sleep) mode. A wakeup message generated by the master, or by any of the slaves, wakes up all the
devices on the network. This is a global message targeting all the slaves in the network.
Change-Frequency command - Upon receiving Change-Frequency command, the device shall switch
from its current operational frequency to the other. This command is a global command targeting all the
slaves in the network.
4.1.1
Command structure
The structure of the five types of commands is detailed below.
Command type 1: Write command.
The Write command consists of 5 bytes: sync break, sync field, Identifier, data and checksum.
Upon receiving a write command, if checksum and protection bits calculations are successful, the data
byte content is transferred to the corresponding output pins.
Sync break: Sync break length is at least 13 bit times with compliance to Lin protocol.
Identifier byte: Consist of 2 protection bits (MSB),"01" bits and 4 ID bits - {P1, P0, '0','1', ID [3:0]}
Protection bits calculation:
P0 = (Identifier [0]) XOR (Identifier [1]) XOR (Identifier [2]) XOR (Identifier [4])
P1 = ~ ((Identifier [1]) XOR (Identifier [3]) XOR (Identifier [4]) XOR (Identifier [5]))
Checksum calculation:
The checksum is an inverted 8 bit sum of the Identifier and Data byte including (own) carry:
Checksum = ~ (Identifier Byte + Data Byte + Carry)

DS-SIG61 R1.01
Write Command Example
Sending Write command of Data byte 0xFF to a device with ID '4' will be calculated the following way:
P0 = ('0' XOR '0' XOR '1' XOR '1') = '0'
P1 = ~ ('0' XOR '0' XOR '1' XOR '0') = '0'
Identifier Byte = '00'-'01'-'0100' = 0x14
Checksum = ~ (0x14 + 0xFF + (Carry ='1')) = 0xEB
⇓
Transmitted Command = [Sync Break - 0x55 - 0x14 - 0xFF - 0xEB]
Command type 2: Read command.
The Read command, initiated by the Master, requests the status of the SIG61 input pins.
The Read command from the master consists of 3 bytes: sync break, sync field and identifier.
Identifier byte: consist of 2 protection bits (MSB),"00" bits and 4 ID bits - {P1, P0, '0','0', ID [3:0]}
The two protection bits are calculated as described above.
If header detection is correct (including protection bits), the SIG61 device (whose ID matches the one in
the command) shall respond by sending two bytes. A data byte containing the status of its eight input
Signal pins followed by a checksum byte. The checksum calculation is carried out as in the description
above while part of it, the identifier byte, was transmitted by the Master. Figure 4.2 shows a generic
Read command.

Command type 3: Read-change
The Read-change command is similar to the Read command. However, it enables to detect any change
in the input pins (pulse-like behavior) that may have occurred between two consecutive Read or Readchange commands. The command from the master instructs the SIG61 to send back information on
changes of its input pins since the last Read or Read-change command. The first change on the pin
after the Read command sets its bit value.
Figure 4.3 shows the process of determining the sent bit value of an input pin.

The Read-change command from the master has 3 bytes: sync break, sync field and identifier.
Identifier byte: consist of 2 protection bits (MSB),"10" bits and 4 ID bits - {P1, P0, '1','0', ID [3:0]}
The response for this command is a data byte containing the SIG61`s input pins recent changed value,
followed by the checksum byte. See checksum and protection bits calculation description above. Figure

Command type 5: Change Frequency command.
This type of command consists of 5 bytes - sync break, sync field, “FE” Hex, “00” Hex and checksum.
The change frequency command identifier is “FE” Hex and the following data byte is “00”Hex.
Upon reception of sync break, sync field, “FE” Hex and “00” Hex bytes the frequency changes from F1
to F0, or vise versa. Checksum calculation follows the description above.

Power Management
The SIG61 device features Sleep mode for power saving. Entering the Sleep mode, as well as waking
up, can be initiated locally, by means of dedicated input pins, or remotely through activity (proper
messages) over the bus.
4.2.1
Entering Sleep mode
The SIG61 can enter sleep mode by any of the following ways:
1. The device nSleep pin is lowered.
2. Sleep command from a remote master is received.
3. The AutoSleep pin is set HIGH and no reception occurred for about 8 seconds.
4.2.2
Device Outputs during Sleep
During Sleep mode, the SIG61 8 output pins remain unchanged if the device has entered this mode
due to a Sleep command from the Master or by lowering the Pin nSleep.
However if the device entered the Sleep mode due to the AutoSleep function, SIG61 will lower all the
outputs to "0".

Remote wake up process
The SIG61 can be awakened by a remote SIG60 master, or SIG61 slave, device transmitting a wakeup
message over the bus. During Sleep Mode, the SIG61 wakes up periodically, every 32mSec, to sense
for bus activity. If a wakeup message is detected, the SIG61 device raises pin INH and lowers pin HDO.
If nSleep pin is low upon remote waking up, the local host (a device controlling the SIG61) which initially
pulled nSleep pin down, must raise the nSleep back high. Figure 4.7 provides the signal description.

Wakeup from Wake pin
A transition seen on the Wake pin (caused by an external source) is used to wake up the device. The
device then enters Standby mode, it rises pin INH, and transmits a wakeup message to the bus. While
transmitting the wakeup message, the device lowers pin HDO. After the transmission is completed the
device raises pin HDO. This is depicted in Figure 4.8. After the transmission is completed the device
enters Normal mode. If nSleep pin is low upon waking up, the local host which initially pulled nSleep pin
down, must raise the nSleep back to high.
