The CXD2545AQ is a digital servo processing IC produced by the Japanese Sony company which is widely used in CD, VCD players. 1.Its functional features. The CXD2545AQ IC has internal 32KB RAM which can absorb the frame jitter as wide as 128 frams. By using new powerful error-correction algorithm software it could achieve double error-correction in C1 and four times error-correction in C2. This would be significant for the VCD films with not high quality. It could play with four times speed, double times speed and variable speed. The constant speed capstan servo processor uses 18 times oversampling digital filter and noise shaping technology. So that the digital servo phase-locked loop would work more stable and more accuracy. This makes the spindle machine could be controlled precisely. The laser head would keep a constant wire-speed relative to the disc so that it could read the information successfully.
