Description
The TMC2250A is a flexible high-performance nine-multiplier
array VLSI circuit which can execute a cascadeable 9-tap
FIR filter, a cascadeable 4 x 2 or 3 x 3-pixel image convolu-
tion, or a 3 x 3 color space conversion. All configurations
offer throughput at up to the maximum guaranteed 50 MHz
clock rate with 12-bit data and 10-bit coefficients. All inputs
and outputs are registered on the rising edges of the clock.
The 3 x 3 matrix multiply or color conversion configuration
can perform video standard conversion (YIQ or YUV to
RGB, etc.) or three-dimensional perspective translation at
real-time video rates.
The 9-tap FIR filter configuration, useful in Video, Telecom-
munications, and Signal Processing, features a 16-bit cascade
input to allow construction of longer filters.
The cascadeable 3 x 3 and 4 x 2-pixel image convolver func-
tions allow the user to perform numerous image processing
functions, including static filters and edge detectors. The 16-bit
cascade input port facilitates two-chip 50 MHz cubic convo-
lution (4 x 4-pixel kernel).
The TMC2250A is fabricated in a sub-micron CMOS process
and operates at clock speeds of up to 50 MHz over the full
commercial (0°C to 70°C) temperature and supply voltage
ranges. It is available in 120-pin Plastic Pin Grid Array
(PPGA) packages, 120-lead Ceramic Pin Grid Array pack-
age (CPGA), 120-lead PQFP to PPGA package (MPGA) and
120-lead Plastic Quad FlatPack (PQFP). All input and output
signals are TTL compatible.
