1 / 20 page  www.fairchildsemi.com REV. 1.1.3 10/25/00 Features • 50 MHz (20ns) pipelined throughput • 3 Simultaneous 12-bit input and output channels (64 Giga {236} colors) • Two's complement inputs and outputs • Overflow headroom available in lower resolution • 10-bit user-defined coefficients • TTL compatible input and output signals • Full precision internal calculation • Output rounding • On-board coefficient memory • Submicron CMOS process Applications • Translation between component color standards (RGB, YIQ, YUV, etc.) • Broadcast composite color encoding and decoding (all standards) • Broadcast composite color standards conversion and transcoding • Camera tube and monitor phosphor colorimetry correction • White balancing and color-temperature conversion • Image capture, processing and storage • Color matching between systems, cameras and monitors • Three-dimensional perspective translation Description A 50-MHz, three-channel, 36 bit (three 12-bit components) colorspace converter and color corrector, the TMC2272A uses 9 parallel multipliers to process high-resolution imagery in real time. The TMC2272A also operates at any slower clock rate and with any smaller data path width, allowing it to handle all broadcast and consumer camera, frame-grabber, encoder/ decoder, recorder and monitor applications as well as most electronic imaging applications. A complete set of three 12-bit samples is processed on every clock cycle, with a five-cycle pipeline latency. Full 23-bit (for each of three components) internal precision is provided with 10-bit user-defined coefficients. The coefficients may be varied dynamically, with three new coefficients loaded every clock cycle. (The full set of nine can be replaced in three clock cycles.) Rounding to 12 bits per component is performed only at the final output. This allows full accuracy with correct rounding and overflow headroom for applications that require less than 12 bits per component. The TMC2272A is fabricated in a submicron CMOS process and performance is guaranteed over the full operating tem- perature range. It is available in a 120-pin Plastic Pin Grid Array (PPGA) package, 120-pin Ceramic Pin Grid Array (CPGA), 120-pin MQFP to PGA package, and 120-pin Plastic Quad FlatPack (PQFP) in three speed grades.
