Overview
Ordering number : ENN7734 SANYO Semiconductors DATA SHEET CMOS IC LC78604E Compact Disc Player DSP with Built-in Microcontroller Overview The LC78604E CMOS IC implements the signal processing, servo control, LED display, button state acquisition, and remote controller handling required by compact disc players without requiring a separate microcontroller.
It provides the following basic functions: demodulation of the EFM signal from the optical pickup, deinterleaving, error detection and correction, 8× oversampling audio filters, D/A converter (with built-in analog low-pass filter), LED display drivers, key acquisition (A/D) and control processing, and automatic discrimination and playback of CD-RW discs.
Thus the LC78604E is ideal for implementing low-end CD players that support playback of CD-RW discs.
The LC78604E also provides a radio tuner frequency display function, and allows digital display of the selected frequency in manual tuning CD radio/cassette players.
Functions • Implements the CD play/pause, stop, track selection, fast forward/fast rewind, repeat 1/repeat all, program setup/play/clear for up to 30 tracks, and shuffle play functions controlled from CD player buttons.
• The signal-processing block applies slicing at the correct level to the input HF signal, and converts that signal to an EFM signal.
At the same time it generates a PLL clock signal with an average frequency of 4.
3218MHz by comparing the phase with that of the internal VCO.
• A reference clock signal and all necessary timings can be generated using an external 16.
9344MHz crystal.
• The disc motor speed is controlled by a frame phase difference signal created from the playback clock and the reference clock.
• Performs frame sync signal detection, protection, and interpolation to assure stable data readout.
• Demodulates the EFM signal and converts the result to 8-bit symbol data.
• Separates the subcode data from the EFM signal and outputs that data to the intern...
