Analog to digital converter with audio embedding for fiber transport
VS662-DAC-SFP
Overview
The VS662 provides the most cost-effective, flexible, and future-proof method of adapting analog video and audio fiber transport in an evolving environment. The VS662 serves as a gateway to transport legacy analog video and audio over existing fiber infrastructure. This allows users to provide analog video services without costly special-purpose conversion and transport cards. Completely standards based, deployment of single ended solutions allow unmatched flexibility where systems can be customized using a VS662 to feed to a multitude of processing and transport systems.
- Transparent fiber transport for NTSC/PAL/PAL-M
- Composite analog video is converted into SD-SDI using 12 bit processing for optimum linearity and SNR
- On-board test pattern generator (SDI, audio tone) and signal integrity checks (EDH) for link commissioning
- Signal jitter management to ensure highest signal integrity
