Overview

The LC89051V is for use in IEC958 format data transmission between digital audio equipment. This LSI is used on the receiving side, and handles synchronization with the input signal and demodulation of that signal to a normal format signal.

Features

• On-chip PLL circuit synchronizes with the transmitted

IEC958 format signal.

• Low-voltage operation (3.3 V)

• Provides 128fs, bit, and L/R clock outputs.

• System clock can be selected to be either 384fs or 512fs.

• Microcontroller interface code settings for different

output types

— Input pin, emphasis output, input bi-phase data

output, and validity flag output settings

— Audio data output format setting

— Channel status output (32-bit output for consumer

products)

— Subcode Q output with CRC flags (80 bits)

— Start ID and shortening (skip) ID detection for DAT

with subcodes

• The built-in VCO can receive at speeds up to twice fs

only when operating from a 5-V power supply.

• Miniature package: SSOP-24
