Grass valley 8950DAC DATASHEET

8950DAC Component D-to-A Converter 71

Key Features

•10-bit D-to-A converter

•4X over-sampling for outstanding resolution

•Independent component gain adjustment

•EDH detection to track signal errors

•2.5 lines output phasing

•Supports all popular CAV formats

•Selective vertical blanking

•SDI passive loop-through input

•Remote control via Ethernet frame I/F

Use the 8950DAC to display a serial component digital signal on an analog RGB monitor, to record a digital video signal to an analog component VTR, or to send digital video to a component analog switcher. The 8950DAC is compact and fits in the 8900-V frame.
