CMOS IC
www.DataSheet4U.com LC78637E „ Overview CMOS IC for Compact Disc Player Applications The LC78637E combines audio CD RF signal processing, servo control, EFM signal processing, audio signal processing, and a CDTEXT decoder in a single chip, enabling a system to be configured with very few peripheral components. The RF signal processing block performs such functions as EFM signal generation, error signal generation, and laser power control. The servo control block carries out A/D conversion of focus error and tracking error signals from the RF signal processing block, and digitally performs focus, tracking, sled, and spindle servo processing necessary for CD servo operation. The functions ...
