SIG60 Evaluation Board for prototyping a multiplex UART or LIN network and testing its communication performance over the DC power line

SIG60 Evaluation Board

The small size evaluation board has a built-in 3.3V switching power supply operating between 10V and 36V. A host connector allows a seamless interface with any uC UART port through HDI, HDO, and HDC digital pins.  The DC-BUS test software with two USB interface boards is available to perform a system test over the user's DC power line in minutes.


The received data signal from the DC  power line passes through a protection network into the RxIn input pin to an Rx amplifier. The amplified signal passes via F0B or F1B pins to an external ceramic filter and back into RxP input. The SIG60 decodes the data from the noisy power line and output it to HDO pin as an asynchronous bit stream.

On the transmitter side, the host sends UART or LIN based data to the SIG60 via HDI pin. The asynchronous data is protected against errors and modulated by the SIG60 modem. The DTXO pin outputs the digitally phase modulated signal to the ceramic filter for shaping. The shaped signal enters the SIG60 via F0B or F1B pins into an output amplifier. The modulated data on TxO pin is conducted over the powerline via the protection network and an external coupling capacitor.

The switching power supply provides the 3.3V voltage required for the SIG60 operation. The power supply operates in a wide input voltage range between 10V and 36V. The module current consumption is in the range of 30mA depends on supply voltage.
