See how this modular product fits in a frame:

The 7730DAC line of serial digital video to component analog converters are broadcast quality D to As with an extensive list of additional features. High quality digital to analog conversion of audio can be packaged with the video to create a D to A frame synchronizer with audio demux. In addition, Evertz fault monitoring processing will analyze and report video and audio problems via an On-Screen-Display, or remotely via VistaLINK® SNMP.


  • D to A process:

  • 12-bit, over sampled video DACs
  • SMPTE/EBU N10, Betacam, MII and NTSC specific standards supported
  • Y, Pb, Pr or G, B, R output format
  • Selectable setup pedestal
  • Black level and gain controls of all components
  • 300mV separate composite sync output
  • The Features of all 7730DACs are:

  • SDI 525 or 625, 270MB/s component digital video input
  • One 270MB/s re-clocked SDI output
  • Four output BNCs for Y, Pb, Pr or G, B, R and composite sync
  • One composite analog output on BNC for monitoring and control
  • One frame video synchronizer (with +S option)
  • Infinitely variable output phase (27MHz clock increments)
  • Freeze modes: black, freeze, pass
  • Menu adjustable free running frequency
  • VU/PPM bar graph level Indicators
  • Decodes vertical interval time code (VITC) and "burns" the time code into the monitoring output picture
  • A comprehensive on-screen display is available to configure the various features of the module
  • Flexible configuration of the text and audio bar graph information displays
  • An extensive list of error conditions can be monitored and fault conditions can be configured from these conditions
  • On-screen messages can be triggered by the configured fault conditions
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • The Features of "-A4" option are:

  • One group (four channels) of synchronous 20-bit audio is de-multiplexed from the incoming digital video
  • Two unbalanced AES audio inputs (up to 48kHz, 24 bits) on BNC
  • User selects either the de-embedded audio or the input AES audio
  • The selected audio is delayed equivalently to the video delay with the +S option
  • Four high quality 24-bit audio channels are output (analog) as balanced on two removable barrier strips
  • Low impedance outputs (66Ω)
  • Analog audio output levels are adjustable
  • Additional audio delay of up to five seconds
  • Additional audio advance of up to one frame, depending on video delay
  • Loss of video modes: pass audio, mute audio
