CLC031A is a video deserializer/descrambler produced by Cirrus Logic, which supports SMPTE292M, 259M, and 344M standards
The CLCO31A is a SMPTE 292M/259M digital video deserializer and descrambler that converts high‑speed serial video streams to parallel data with built‑in FIFO, ancillary data extraction and automatic format detection. It operates from a 2.5 V core supply and 3.3 V I/O, dissipating about 850 mW, and is offered in a 64‑pin TQFP package.
The device supports data rates from 270 Mbps up to 1.485 Gbps, includes a Built‑In Self‑Test (BIST) and video Test Pattern Generator, and provides flexible I/O for configuration and control. Detailed electrical characteristics, pin assignments and recommended application circuits are provided throughout the document.
