CS8406

192 kHz Digital Audio Interface Transmitter

Features

General Description

The CS8406 is a monolithic CMOS device which en-

codes and transmits audio data according to the AES3,

IEC60958, S/PDIF, or EIAJ CP1201 standards. The

CS8406 accepts audio and digital data, which is then

multiplexed, encoded, and driven onto a cable.

 Complete EIAJ CP1201, IEC-60958, AES3,

S/PDIF-compatible Transmitter

 +3.3 V or 5.0 V Digital Supply (VD)

 +3.3 V or 5.0 V Digital Interface (VL)

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

input port. The channel status and user bit data are in-

 On-Chip Channel Status and User Bit Buffer

put through an SPI™ or I²C microcontroller port, and

Memories Allow Block-Sized Updates

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.

 Flexible 3-Wire Serial Digital Audio Input Port

 Up to 192-kHz Frame Rate

The CS8406 is available in 28-pin TSSOP, SOIC, and

QFN packages in both Commercial (-10º to +70ºC) and

Automotive grades (-40º to +85ºC). The CDB8416

Demonstration board is also available for device

evaluation and implementation suggestions. Please

refer to “Ordering Information” on page 37 for complete

details.

 Microcontroller Write Access to Channel Status

and User Bit Data

 On-Chip Differential Line Driver

 Generates CRC Codes and Parity Bits

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

receivers, digital mixing consoles, effects processors,

set-top boxes, and computer and automotive audio

systems.
