TC9495F

Digital Servo Single Chip Processor Built in 1 Bit DA Converter

The TC9495F is a single chip processor which incorporates the

following function: synchronous separation protection and

interpolation, EFM demodulation, Error correction, micro

controller interface, digital equalizer for use in servo LSI and

servo control circuit.

In addition, the TC9495F incorporates a 1 bit DA converter. In

combination with the head amplifier TA2109F, TA2150FN,

TA2153FN for digital servo, the TC9495F allow simplified,

adjustment-free structuring of CD player system.
