CXD2720Q-2

Single-Chip Digital Signal Processor for Karaoke

Description

100 pin QFP (Plastic)

The CXD2720Q-2 is a digital signal processor LSI

for Karaoke, suitable for use in LD/CD/CD-G/video

CD and the like.

A large capacity DRAM and AD/DA converters are

built in, and Karaoke functions such as key control

and microphone echo are contained on a single

chip.
