3. GENERAL DESCRIPTION
The CS8415A is a monolithic CMOS device which receives and decodes audio data according to the AES3,
IEC60958, S/PDIF, and EIAJ CP1201 interface standards.
Input data is either differential or single-ended. A low-jitter clock is recovered from the incoming data using a PLL.
The decoded audio data is output through a configurable, 3-wire output port. The channel status and user data are
assembled in block-sized buffers and may be accessed through an SPI or I²C microcontroller port. For systems
with no microcontroller, a stand-alone mode allows direct access to channel status and user data output pins.
Target applications include AVR, CD-R, DAT, DVD, multimedia speakers, MD and VTR equipment, mixing con-
soles, digital audio transmission and receiving equipment, high-quality D/A and A/D converters, effects processors,
set-top boxes, and computer audio systems.

AES3 and S/PDIF Standards Documents
This data sheet assumes that the user is familiar with the AES3 and S/PDIF data formats. It is advisable to
have current copies of the AES3 and IEC60958 specifications on hand for easy reference.
The latest AES3 standard is available from the Audio Engineering Society or ANSI at
www.ansi.org. Obtain the latest IEC60958 standard from ANSI or from the International Electrotechnical
Commission at www.iec.ch. The latest EIAJ CP-1201 standard is available from the Japanese Electronics
Bureau.
Cirrus Logic Application Note 22: Overview of Digital Audio Interface Data Structures contains a useful tu-
torial on digital audio specifications, but it should not be considered a substitute for the standards.
The paper An Understanding and Implementation of the SCMS Serial Copy Management System for Digital
Audio Transmission, by Clifton Sanchez, is an excellent tutorial on SCMS. It is available from the AES as
preprint 3518.
