A High Speed Digital Filter LSI for Video Signal Processing

Abstract

A ninth-order symmetrical FIR filter has been developed for use in two-dimensional TV video signal processing. The order and the transfer function of the filter can be altered through the external terminals. The chip, achieved through 2 μm CMOS technology, contains about 52,000 transistors and occupies an area of 50 mm ² . It operates at a high clock frequency of 33 MHz, and dissipates only 600 mW of power.
