  • Page 10: Overview

    Overview The ADC-8032B is a 10-bit broadcast quality decoder with a 12-bit analog to digital converter. It is specifically designed for broadcast or production situations in which an analog PAL-B, PAL-M, PAL- N, or NTSC composite signal must be converted to a component SDI signal. Four SDI outputs are provided.

    8032B-S. (RossGear ADL-8520 AES/EBU Auto Tracking Audio Delay) The Tracking Delay Pulse is a positive 5V pulse. Its width tracks the video delay as it passes through the card. The ADC-8032B tracking delay pulse tracks up to 2 video lines, the ADC-8032B-S up to 2 fields.

  • Page 17: User Controls

    User Controls In This Chapter This section contains a description of the ADC-8032B user controls. The ADC-8032B uses card edge controls for changing operational Note parameters. The card defaults with switch access set to the locked position. Refer to the “Bank A - F: Lock/Unlock Switch Access” section in Chapter 4, “Using Banks”, before attempting to make any adjustments.
  • Page 18 4, “Using Banks” for complete details. Mode Select Switch – SW2 The (SW2) Mode Select switch is used to enable, disable, and select specific ADC-8032B functional modes, or configurations, within the operational function menu (selected first with the SW1 Function Select switch). The Mode Select switch is a 3-position momentary toggle switch with an automatic spring-return to the center position.
  • Page 19 • Off = No external reference is present FREEZE Yellow When lit, this LED indicates that the output is frozen (ADC-8032B-S only). When lit, this LED indicates that Switch Access is unlocked. ADC-8032B controls ACCESS Yellow (See Bank A, B, and C Functions) are accessible.

    About the Timing Mode • Timing Mode Summary • Bank C-1: Timing Mode Procedure About the Timing Modes The ADC-8032B and ADC-8032B-S offer two sets of timing modes; Line Delay/Sync and Frame Delay/Sync. 4-14 • Using Banks ADC-8032B User Manual (Iss. 02B)
  • Page 35 This is very useful in that all sources to the ADC-8032B (for example, from a routing switcher) only need to be lined up to the same line.
  • Page 36 Whether a synchronous or an asynchronous source is used, output timing is constant. The delay through the card will be the minimum latency (in the order of microseconds) to a full frame of delay. 4-16 • Using Banks ADC-8032B User Manual (Iss. 02B)

  • Page 37: Timing Modes

  • Page 42 Bank C-B: Hotswitch Mode The ADC-8032B 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. It can take several fields before the PLL can regain lock, and until it does so, the decoder cannot properly decode the incoming video.
  • Page 43 In all other cases, the output timing will be disturbed any time an untimed switch is made at the input of the ADC-8032B. This function sets the mode or disables it. Three choices are available: •...

  • Page 45: 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-8032B 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 46: Jumper Setup

    Jumper Setup If fault reporting for the ADC-8032B is desired, use jumper JP5 - 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.
