SC9638EP
CD SERVO CONTROLLER WITH MCU
(WITH CLOCK AND RADIO FREQUENCY DISPLAY)
DESCRIPTION
The SC9638EP is a chip for CD player with clock and alarm clock. It
has mature functions and provides the functions of CD play, radio
frequency display, clock display, automatic sleep power off and double
alarm bell power on and etc. The chip supports CD digital servo control,
CD signal processing, frequency counting display for radio receiver,
digital auto frequency DAC output, and LCD directly driving. The
periphery circuit of the chip is simple and the cost is low.
