TC9490F/FA
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9490F, TC9490FA
Digital Servo Single-Chip Processor for Use in CD Player
TC9490F/FA is a single-chip processor which incorporates the
following functions: sync separation protection, interpolation,
EFM decoder, error correction, microcontroller interface, digital
equalizer for use in servo LSI, and servo control circuit.
TC9490F/FA also incorporates a 1-bit DA converter.
Combining TC9490F with digital servo head amp TA2147F
enables very simple and completely adjustment-free CD player
systems.
