7730ADC & 7730ADC-A4

The 7730ADC line of component analog video to serial digital converters are broadcast quality A to Ds with an extensive list of additional features. High quality analog to digital conversion of audio inputs can be packaged with the video to create a A to D frame synchronizer 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 7730ADC (1 slot module) and 7730ADC-A4 (2 slot module) can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

特点|

• A to D process

• 10 bit, 54MHz 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 three components, gain control on all three components, inter-channel delay control in 18ns increments
• Sync on green or separate sync input
• 300mV or 4V separate sync support

• Features of all 7730ADCs are:

• Three input BNCs for YPbPr or RGB input
• One sync input BNC for separate sync
• Two SDI 525 or 625, 270MB/s component digital video output Without OSD text or audio bar graphs
• One combination output that can either be an extra SDI output or composite analog video output
• When configured as a composite analog output it can either be a clean output (no OSD) or have the OSD text and bar graph graphics for monitoring
• EDH encoding on SDI output
• One combination input BNC that can either be an LTC input or a composite analog reference input (NTSC or PAL-B)
• 75Ω or Hi-Z, jumper configurable input impedance
• 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 OSD Monitoring output
• 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
• Fault conditions are reported via VistaLINK® SNMP
• VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller

• 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 equivalent video delay (with +S option)
• Additional audio delay of up to five seconds
• Audio advance of up to one frame less three microseconds
• One group (four channels of audio) is multiplexed on the outgoing digital video
• Two unbalanced AES audio outputs delayed equivalently to the video delay
• 75Ω coaxial (unbalanced) DARS reference input on BNC
• Loss of video modes: pass audio, mute audio
