1.5.1. Connection and Settings Guidelines

Before programing with the .sof file, ensure that the connections and settings are correct.
  • For parallel loopback design, the on-board BNC RX connector (J1/12G In) connects to an external video source and the on-board BNC TX connector (J2/12G Out) connects to a video analyzer.
  • For serial loopback design, the on-board BNC TX connector (J2/12G Out) connects to an on-board BNC RX connector (J1/12G In) or a video analyzer.
  • Ensure all switches on the development board are in default position.
  • The SDI video analyzer displays the video generated from the source.
    Note: For parallel loopback designs, change the jumper (J8) position before switching between fractional frame rate and integer frame rate video formats. Press the push button (PB1) to trigger a device (LMK03328) power cycling through the PDN pin every time you change the jumper (J8) position.

1 Si5340_INSEL0
  • Si5340_INSEL1, Si5340_INSEL0 = [0,0]

    Use crystal as PLL input for Si5332 (default)

  • Si5340_INSEL1, Si5340_INSEL0 = [1,0]

    Use external SMB as PLL input for Si5332

2 Si5340_INSEL1

J8 To switch the generated clock frequency for the TX channel:
  • Pin 1–2 = 297 MHz
  • Pin 2–3 = 297/1.001 MHz
J9 To select SDI or IP mode:
  • Pin 1–2 = SDI mode
  • Pin 2–3 = IP mode
