The DES6800+D is a compact, high-precision, 12-bit decoder that converts NTSC and PAL analog composite signals into superior-quality component (4:2:2) digital video.

Utilizing the advanced Imagine® Phase Quadrature Mixing (PQM™) technology for 2D adaptive comb filtering, coupled with TBC (time-base correction) capabilities, this card is designed for high performance and optimal value. It processes vertical blanking lines and handles super-black levels.

Part of the 6800+™ core processing platform, the DES6800+D module includes frame synchronization and TBC features. It provides an audio sync clock with video delay and hot-switch outputs for an audio sync interface to accommodate audio processing modules, including the MSA6800+ embedder series and ADS6800+ audio delay/A-to-D series modules.

The DES6800+D modules can be controlled at the card edge, or controlled and monitored via the CCS Navigator™ software application, HTTP web browser, or NUCLEUS™ hardware control panels, or via third-party control applications using SNMP.
