TC94A09F
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC94A09F
Single-Chip CD Processor with Built-in Controller
The TC94A09F is a single-chip CD processor for digital servo.
The IC has a built-in 4-bit microcontroller.
The controller features an LCD/LED driver, 4-channel 6-bit AD
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.
The CD processor incorporates sync separation protection and
interpolation, EFM decoder, error correction, digital equalizer for
servo, and servo controller. The CD processor also incorporates a
Weight: 1.6 g (typ.)
1-bit DA converter. In combination with a RF amp TA2153FN
and TA2109F, the TC94A09F can very simply configure an adjustment-free CD player.
Thus, the IC is suitable for CD systems for automobiles and radio-cassette players.
