Featuring two independent channels of high quality 12 bit A-D conversion with 5-line adaptive comb filtering the C AD 5122 is an excellent choice for composite to SDI decoding for the most demanding broadcast applications. The C AD 5122 utilizes the very latest analog and digital signal processing technology to provide unmatched performance and feature sets. The integrated frame synchronizer with 8 frames of programmable delay is ideal for timing asynchronous composite analog sources into digital switchers, routers or other downstream digital equipment.

Flexible genlock capability provides high quality VCXO genlock for broadcast quality sources but also has a mode for lower quality consumer grade sources video (such as VHS and DVD). Combine this with the multi-standard capability (PAL/NTSC) makes this the most flexible converter for use in any application with almost any composite video source.

The new CTI feature dramatically improves decoded image quality by improving chrominance transitions. When combined with the 5-line adaptive comb filter, practically all composite cross color artifacts are removed from the conversion.

Microprocessor control and on board flash ram enable configurations and settings to be stored within the module (through power cycles and module removal). Local control capability is provided via the integrated alphanumeric display and control switch. Access to extended feature sets, remote control, status monitoring and error reporting is possible when using the APPolo control system
