Ordering number : ENN6329 CMOS IC LC78628E Compact Disc Player DSP with Built-in HDCD Decoder ® Overview The LC78628E CMOS IC implements signal processing and servo control for compact disc players, laser disc players, CD-V, CD-I, and similar products. It provides functions for demodulation of the EFM signal from the optical pickup, deinterleaving, error detection and correction, and processing servo system commands issued by the system microprocessor. In addition to this basic CD functionality, it also provides HDCD (High Definition Compatible Digital) decoding functions and CD text functions. It also includes a built-in EFM PLL circuit. • Performs detection, protection, and interpolation for the frame synchronizing signal to assure stable data readout. • Demodulates the EFM signal, converting it to 8-bit symbol data. • After applying a CRC check to the subcode Q signal, outputs that data to the control microprocessor using serial data transfer.
