TMC2272A

Digital Colorspace Converter

36 Bit Color, 50 MHz

Features

Applications

• 50 MHz (20ns) pipelined throughput

• 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

• 3 Simultaneous 12-bit input and output channels

(64 Giga {2 } 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

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.

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 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.

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.

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
