Product ManualManual

The 7730ADC-HD line of component analog video to serial digital converters are broadcast quality high definition A to Ds with an extensive list of additional features. High quality analog to digital conversion of audio or AES inputs can be packaged with the video to create an A to D with audio embedder. In addition, Evertz fault monitoring processing will analyze and report video and audio problems via an On-Screen-Display, or remotely via VistaLINK® SNMP.


  • The Features of the A to D process:
  • 10 bit, 74.25MHz (/1.001) sampling of input video
  • Internal processing to maintain 10-bit digital video quality
  • Y, Pb, Pr or G, B, R input support
  • Black level clamp on all components
  • User-adjustable input video processing functions: black level control on all components, gain control on all components, inter-channel delay and picture position control in 13.5ns increments
  • Sync on green or separate sync input
  • The Features of all 7730ADC-HDs are:
  • Three input BNCs for Y, Pb, Pr or G, B, R input
  • One sync input BNC for separate sync
  • Two HD SDI 74.25 or 74.176MB/s component digital video output without OSD text or audio bar graphs
  • One combination output that can either be an extra HD SDI output or composite analog video output
  • When configured as a composite analog output it will be a clean output (no picture) and have the OSD text and bar graph graphics for monitoring
  • One line video synchronizer
  • Variable output phase (in clock increments)
  • Loss of video modes: black, pass
  • A comprehensive on-screen display is available to configure the various features of the module
  • 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:
  • Four balanced analog audio inputs on two removable barrier strips
  • High impedance inputs (user supplies termination resistors for other impedances)
  • Analog audio input levels are adjustable
  • Jumpers set coarse input levels, fine input levels are set by software control
  • Audio delay of up to five seconds
  • One group (four channels of audio) is multiplexed on the outgoing digital video
  • Two unbalanced AES audio outputs delayed equivalently to the embedded audiodelay
  • 75Ω coaxial (unbalanced) DARS reference input on BNC
  • Loss of video modes: pass audio, mute audio
