1.2.2.2. Parallel Loopback

To run the parallel loopback demonstration:

  1. Connect an SDI signal generator to the channel 0 receiver input of SDI_RX_P (J20).
  2. Connect an SDI signal analyzer to the channel 0 transmitter output of SDI_TX_P (J21).
  3. Check the result on the SDI signal analyzer.
This test uses the following user LEDs to indicate the respective conditions:
  • D8, D9 and D10 indicate the receiver signal standard.
  • D7 illuminates when the align_locked signal for channel 0 is asserted.
  • D6 illuminates when the trs_locked signal for channel 0 is asserted.
  • D5 illuminates when the frame_locked signal for channel 0 is asserted.
