LC8904 Overview
EN 5014B CMOS LSI LC8904Q Digital Audio Interface Receiver Preliminary 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.
LC8904 Key Features
- Synchronizes with the transmitted EIAJ format signal using a built-in PLL circuit
- Modes are set up and codes are output according to mands 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
