optional FPGA-IO
The AMC825 features four electrically isolated CAN High-Speed interfaces according to
ISO 11898. Local data control and management is controlled by an FPGA. Optional the FPGA is
available with integrated 32-bit soft microcontroller (MicroBlazeTM).
The AMC825 provides high resolution hardware timestamps.
The IRIG-B interface offers inputs for analogue or RS-422 compatible IRIG-B coded signals at
the front panel. Both are electrically isolated.
Additionally a digital input (RS-422 compatible) for IRIG-B is available at the PMC connector
Pn4 (without electrical isolation).
IRIG-B evaluation is controlled by an additional microcontroller.
For the 25-pin DSUB connector in the front panel an adapter cable to 9-pin DSUBs for CAN and
IRIG-B (analogue and RS-422 compatible) is available.
