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 process

• Package: QFP-48E
