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.
