CLC031VEC

Video Processing Overview

The CLC031VEC is a monolithic SMPTE 292M/259M digital video deserializer and descrambler featuring integrated video and ancillary data FIFOs. It converts serial component video data into parallel formats, supporting rates of 270 Mbps, 360 Mbps, 540 Mbps, 1.483 Gbps, and 1.485 Gbps with auto-detection. The device outputs 10-bit parallel data for SDTV or 20-bit parallel data for HDTV, synchronized with a word-rate clock. It includes clock/data recovery, NRZI-to-NRZ conversion, CRC/EDH checking, and LSB de-dithering. Powered by separate 2.5V logic and 3.3V I/O supplies, it dissipates typically 850mW and is housed in a 64-pin TQFP package.

Video Processing Procurement Notes

Verify the specific ordering suffix VEC corresponds to the 64-pin TQFP package configuration. Confirm that the supply voltage requirements align with the recommended operating conditions of +2.5V for logic and +3.3V for I/O circuits. Ensure the application environment remains within the commercial temperature range of 0°C to +70°C. Check for any specific pinout variations or alternative package options if mechanical constraints differ from the standard TQFP footprint.

Video Processing Selection Notes

Select this component when interfacing with SMPTE 292M or 259M serial digital video sources requiring parallel output. It is suitable for designs needing automatic format detection across SD and HD rates. Consider its low power consumption and integrated FIFOs for systems requiring precise video timing adjustments. The device is ideal for applications demanding robust error checking via EDH/CRC and ancillary data extraction capabilities.

Video Processing Part Context

The CLC031VEC is part of the CLC031 series, designed as a complement to the CLC030 serializer. Manufactured originally by National Semiconductor, it serves as a critical interface in professional broadcast and post-production video chains. The device bridges high-speed serial transmission lines with parallel processing units, ensuring signal integrity through advanced clock recovery and scrambling/descrambling functions.
