TC9495F中文资料东芝数据手册PDF规格书

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.
