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.
