lc8902q

Manufacturer Part Number
lc8902q
Description
Digital Audio Interface Receiver
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number : EN4333A
Overview
The LC8902 and LC8902Q are receiver LSIs for
applications in which data is transmitted between digital
audio equipment in the EIAJ format. These LSIs
synchronize with the input signal and demodulate that
signal to a regular format signal.
Features
• Built-in PLL circuit synchronizes with the input EIAJ
• Microcomputer interface receives mode settings and
• Supports both 384 fs and 512 fs system clocks
• Can operate in either digital source mode or analog
• User bit CD subcode interface
• DIP42S and QIP44M packages
• Si gate CMOS process, single 5 V power supply
format signal.
outputs fs codes, copy information, and category codes.
(selectable) and provides 256 fs, 128 fs, BCLK and
LRCK clock outputs.
