Follow these steps to run the test:

  1. Connect the transmitter output, SDO_A (J16), of channel 1 to the receiver input, SDI_RX_P (J20), of channel 0.
  2. Use the SW2 switches to change the input or output type.
This test uses the following user LEDs to indicate the respective conditions:
  • D9 and D10 indicate the internal pattern generator standard, which transmits through channel 1 of the transmitter.
  • D7 and D8 indicate the receiver signal standard.
  • D6 illuminates when the trs_locked signal for channel 0 is asserted.
  • D5 illuminates when the frame_locked signal for channel 0 is asserted.
