µPD64031A

Ghost Reducer for NTSC in Japan


Overview

The µPD64031A is a ghost reducer LSI supporting the GCR mode of Japan. It equalizes the waveform of the video signal including the Japanese GCR signal and reduces ghost.
This LSI integrates all the external peripheral ICs necessary for a µPD6432 system (such as an A/D converter, a D/A converter, a microcontroller, a clock generator, and SRAM) on a single chip.
