Ordering number : EN5502 CMOS LSI LC78625E Compact Disc Player DSP Overview The LC78625E is a CMOS LSI that implements the signal processing and servo control required by compact disc players, laser discs, CD-V, CD-I and related products. The LC78625E provides several types of signal processing, including demodulation of the optical pickup EFM signal, de-interleaving, error detection and correction, and digital filters that can help reduce the cost of CD player units. It also processes a rich set of servo system commands sent from the control microprocessor. It also incorporates an EFM-PLL circuit and a one-bit D/A converter. This LSI is an improved version of the LC78620E.
