Digital Servo Single-Chip Processor for Use in CD Player
TC94A14F/FA/FB is a single-chip processor which incorporates
the following functions: sync separation protection, interpolation,
EFM decoder, error correction, micro controller interface, digital
equalizer for use in servo LSI, and servo control circuit.
TC94A14F/FA/FB also incorporates a 1-bit DA converter.
Combining TC94A14F/FA/FB with digital servo head amp
TA2157F/FN enables very simple and completely adjustment-free
CD player systems.
