Single-chip CD Processor with Built-in Controller

incorporates a 4-bit microcontroller.

converter, 2/3-line serial interface, buzzer, interrupt function, and

8-bit timer/counter. The CPU can select one of three crystal

oscillator operating clocks (16.9344 MHz, 4.5 MHz, and 75 kHz),

facilitating interface with the CD processor.

interpolation, EFM decoder, error correction, digital equalizer for

servo, and servo controller. The CD processor also incorporates a

1-bit DA converter. In combination with RF amp TA2153FN or

TA2109F, TC94A23F can very simply configure an

adjustment-free CD player.

Features

TC94A23F is a single-chip CD processor for digital servo. It

The controller features an LCD/LED driver, 4-channel 6-bit AD

The CD processor incorporates sync separation protection and

Thus, the IC is suitable for CD systems for automobiles and radio-cassette players.
