Player use. It includes a RF amplifier, tracking error
amplifier, focus error amplifier, etc..., on a single chip.
FEATURES
• RF amplifier, tracking error amplifier, focus error
amplifier, APC circuit, and reference amplifier
included on a single chip
• On-chip RF output signal automatic gain control
(AGC) and peak to peak envelop detection
• Single 5V power supply
• 32-pin PLCC package
W88631F
GENERAL DESCRIPTION
W88631F provides CD signal processing decoding
functions and all servo functions needed in a three-spot
CD system. This chip has a high degree of integration to
reduce the number of external components required.

offset, balance)
• Wide range of adjustable servo characteristics
possible
• Built-in access procedure
• Focus automatic start up
• Trackloss, Shock, Defect, Dropout detection
• Fully digital data recovery (digital equalizer, data
slicer, PLL)
• Wide data capture range (+/- 1.5 channel clock, up to
4X speed)
• Wide frame jitter margin (+/- 4 frames) with built-in
deinterleaved SRAM
• EFM protected demodulator
• Digital spindle motor control by CLV
• Error correction capabilities
• Subcode data processing
• Audio data processing, Concealment strategy, digital
attenuation and soft mute
• Audio data output interface
--- standard EBU digital audio output interface
--- D/A converter interface and CD-ROM interface
• Extended general I/O port simplifies system design
