TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9462F
Digital Servo Single Chip Processor
TC9462F
The TC9462F is a single chip processor which incorporates the
following function: synchronous separation protection and
interpolation, EFM demodulation, Error correction,
microcontroller interface, digital equalizer for use in servo LSI
and servo control circuit.
In addition, the TC9462F incorporates a 1 bit DA converter. In
combination with the head amplifier TA2109F, TA2153FN for
digital servo, the TC9462F allow simplified, adjustment-free
structuring of CD player system.
