CAM622 MultiComms Board

CAM622 Test Board with ABN, BiSS, SENT outputs for Type B Sensors

The CAM622 MultiComms Board processes a Type B Sensor.  It supports multiple host interfaces including SPI, quadrature ABN, BiSS and SENT.

The CAM622 MultiComms Board includes the CAM622 IC itself, a step-down power supply for efficient operation from a 5 V input, line transceivers and an iC-Haus iC-MB to support BiSS communication. The BiSS interface uses the same 5 V differential signal lines as quadrature ABN.  This reduces the board space needed for connectors, and allows ABN behaviour to be configured over the ABN lines themselves using BiSS.

The CAM622 MultiComms Board connects to a Type B Rotary Sensor with the 6-way Dual PicoBlade Cable part 013-6019.  Alternatively it connects to a Type B Linear Sensor with the 120mm 6-way PicoBlade-EZMate Cable part 013-6021.

The CAM622 MultiComms Board is available as part of the CAM622 MultiComms Bundle.  This is recommended for getting started with evaluation and development.
