Sanyo Electric LC78625E
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.| Part No. | LC78625E |
