Everything up to (but not including) the first line of active video is considered part of the Vertical Interval and will be affected by this function. In 525- line mode, signals in the vertical interval are passed without setup even if setup is enabled.

    There are two versions of the ADC-8032A available. The standard ADC-8032A can be timed within one line in 37ns increments. The ADC-8032A-S with the frame synchronizer can be timed within one video frame in 37ns increments. The fine phase potentiometer (RV1) is provided for sub-pixel adjustment.
  • Page 32 This is very useful in that all sources to the ADC-8032A (for example, from a routing switcher) only need to be lined up to the same line.

  • Page 33: Timing Modes

    • Output phasing is infinite over a full frame, and the delay through the card varies from the minimum processing delay up to the minimum processing delay plus a full frame. Using Banks • 4-15 ADC-8032A User Manual (Iss. 04)
  • Page 34 Turning the pot clockwise increases delay, whereas turning it counter-clockwise decreases the delay. The range is approximately 45 ns, which is slightly longer than the step size of the H Delay function. 4-16 • Using Banks ADC-8032A User Manual (Iss. 04)

  • Page 38 Bank C-B: Hotswitch Mode The ADC-8032A uses a phase-locked-loop (PLL) to synchronize its pixel clock to the incoming signal’s line rate. Because of this, any disturbance to the incoming line rate, such as an untimed switch outside the lock window of the PLL, will cause the PLL to lose lock.
  • Page 39 In all other cases, the output timing will be disturbed any time an untimed switch is made at the input of the ADC-8032A. This function sets the mode or disables it. Three choices are available: •...

  • Page 41: Smpte 269M Fault Reporting

    The SMPTE 269M Fault Reporting system, also known as an SMPTE “alarm”, provides indication if one or more frame modules encounter a fault or an abnormal condition. The ADC-8032A module provides a jumper to enable SMPTE-269M fault reporting. The card connects by means of an internal interface circuit to an auxiliary telco connector on RossGear 8000 series frames.

  • Page 42: Jumper Setup

    Jumper Setup If fault reporting for the ADC-8032A is desired, use jumper JP4 - 269M Fault Report to set up the card. 1. To access the jumper, remove the card from the frame by pressing down the white card ejector tab and pulling the card from the frame slot.

  • Page 43: Comlink

    PC COM ports. To connect the Comlink between the ADC-8032A and your PC, you require a coax adapter cable with a BNC connector at one end, and either a 9-pin or 25-pin RS-422 or RS-232 connector at the other end.

  • Page 44: Cable Construction

    1. Connect the center conductor of the coax to the pin 3 (RX) on your serial port connector. 2. Connect the shield of the coax to the ground pin 7 (GND) on your serial port connector. 6-2 • Comlink ADC-8032A User Manual (Iss. 04)
