TC94A39FAG/FB
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC94A39FAG, TC94A39FB
Single-Chip CD Processor with Built-in Controller (CD-DX)
The TC94A39FAG/FB is a single-chip CD processor for digital
servo, which incorporates a 4-bit microcontroller.
The controller features an LCD driver, 4-channel 6-bit AD
converter, 1 port 2-channel 2/3-line or UART serial interface
module, a buzzer, 20-bit general-purpose counter function,
interrupt function, and 8-bit timer/counter. The CPU can select
one of four operating clocks (16.9344-MHz, 75-kHz or 32.768-kHz
crystal oscillator and CR oscillator), facilitating interface with the
CD processor.
The CD processor incorporates sync separation protection and
interpolation, EFM demodulator, error correction, digital
equalizer for servo, and servo controller. The CD processor also
incorporates a 1-bit DA converter. In combination with the
TA2157F/FN digital servo head amplifier, the TC94A39FAG/FB
can very simply configure an adjustment-free CD player.
Thus, the IC is suitable for CD systems for automobiles and
radio-cassette players.
