CS8405A

96 kHz Digital Audio Interface Transmitter

Features

General Description

The CS8405A is a monolithic CMOS device which en-

codes and transmits audio data according to the AES3,

IEC60958, S/PDIF, or EIAJ CP1201. The CS8405A ac-

cepts audio and digital data, which is then multiplexed,

encoded and driven onto a cable.

Complete EIAJ CP1201, IEC-60958, AES3,

S/PDIF compatible transmitter

+5 V Digital Supply(VD)

+3 V to 5 V Digital Interface (VL)

On-chip Channel Status and User bit buffer

memories allow block sized updates

Flexible 3-wire serial digital audio input port

Up to 96 kHz frame rate

Microcontroller write access to Channel

Status and User bit data

On-chip differential line driver

Generates CRC codes and parity bits

Standalone mode allows use without a

microcontroller

The audio data is input through a configurable, 3-wire in-

put port. The channel status and user bit data are input

through an SPI or Two-Wire microcontroller port, and

may be assembled in block sized buffers. For systems

with no microcontroller, a stand alone mode allows di-

rect access to channel status and user bit data pins.

Target applications include A/V Receivers, CD-R, DVD

receivers, digital mixing consoles, effects processors,

set-top boxes, and computer and automotive audio

systems.
