Overview
The LC78630E is a CD-DA signal-processing LSI for use
in video CD player systems. The LC78630E incorporates
signal-processing circuits for demodulating and de-
interleaving the EFM signal from the optical pickup, error
detection and correction, and digital filtering. It also
includes a 1-bit D/A converter and executes commands
sent from a system control microprocessor.
Features
Built-in PLL for EFM signal synchronization (a hybrid
analog-digital PLL that supports 4
× playback)
Built-in PLL for variable pitch playback (±13%)
18KB RAM on chip
Error detection and correction (corrects two errors in C1
and four errors in C2)
Frame jitter margin: ±8 frames
Frame synchronization signal detection, protection, and
insertion
Dual interpolation adopted in the interpolation circuit.
EFM data demodulation
Subcode demodulation
Zero-cross muting adopted
Servo command interface
2fs digital filter
Digital de-emphasis
Built-in independent left- and right-channel digital
attenuators (239 attenuation steps)
Left/right swap function
Built-in 1-bit D/A converter (third-order
∑ noise
shaper, PWM output)
Built-in digital output circuit
CLV servo
Arbitrary track jumping (of up to 255 tracks)
Variable sled voltage (four levels)
Built-in oscillator circuit using an external 16.9344 MHz
or 33.8688 MHz (for 4
× playback) element
Supply voltage: 3.6 to 5.5 V (4.5 to 5.5 V for 4
×
playback mode)
Six extended I/O ports and 2 extended output ports
