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. In
addition to supporting low-voltage operation, on/off
control of the de-emphasis function and use of the
bilingual function have been enabled in certain additional
modes.
Functions
• The LC78625E takes an HF signal as input, digitizes
(slices) that signal at a precise level, converts that signal
to an EFM signal, and generates a PLL clock with an
average frequency of 4.3218 MHz by comparing the
phases of that signal and an internal VCO.
• A precise reference clock and the necessary internal
timings are generated using an external 16.9344 MHz
crystal oscillator.
• Disc motor speed control using a frame phase difference
signal generated from the playback clock and the
reference clock
• Frame synchronization signal detection, protection, and
interpolation to assure stable data readout
• EFM signal demodulation and conversion to 8-bit
symbol data
• Subcode data separation from the EFM demodulated
signal and output of that data to an external
microprocessor
• Subcode Q signal output (LSB first) to a microprocessor
over the serial interface after performing a CRC error
check
• Demodulated EFM signal buffering in internal RAM to
handle up to ±4 frames of disc rotational jitter
• Demodulated EFM signal reordering in the prescribed
order for data unscrambling and de-interleaving
• Error detection, correction, and flag processing (error
correction scheme: dual C1 plus dual C2 correction)
• The LC78625E sets the C2 flags based on the C1 flags
and a C2 check, and then performs signal interpolation
or muting depending on the C2 flags. The interpolation
circuit uses a quadruple interpolation scheme. The
output value converges to the muting level when four or
more consecutive C2 flags occur.
