Overview
The LC8904Q demodulates data transmitted between
digital audio equipment in the EIAJ format (CP-1201) to a
normal format signal synchronized with the receiving side
input signal.
Features
Synchronizes with the transmitted EIAJ format signal
using a built-in PLL circuit.
Modes are set up and codes are output according to
commands sent over a microprocessor interface.
-- Input pin and output data format setup
-- Selection of digital source mode or analog source
mode
-- 32-bit channel status output (consumer product
mode 0)
-- 80-bit subcode Q data output (CRC check included)
Either a 384fs or a 512fs clock can be selected as the
system clock.
Provides 256fs, 128fs, BCLK, and LRCK clock outputs.
Implements a CD subcode interface (CP-2401) using
user bits.
Fabricated in a CMOS single-voltage power supply
