MN6626
Signal Processing LSI for CD Players
Overview
The MN6626 is a CD signal processing LSI that, on a
single chip, provides both basic CD player signal pro-
cessing (EFM demodulation, error correction, and CLV
servo) and extra functionality for increasing the versatil-
ity and the performance of the CD player.
