CS8415A-CSZR

Audio Special Purpose Overview

The CS8415A-CSZR is a monolithic CMOS digital audio interface receiver manufactured by Cirrus Logic. It receives and decodes one of seven channels of audio data compliant with IEC60958, S/PDIF, EIAJ CP1201, or AES3 standards. The device features a flexible 3-wire serial digital output port and comprehensive control via a 4-wire microcontroller interface supporting SPI or I²C protocols. It operates on a +5.0 V analog supply (VA+) and a +3.3 V or +5.0 V digital interface supply (VL+). The unit supports sample frequencies from 8 kHz to 96 kHz and includes low-jitter clock recovery mechanisms.

Audio Special Purpose Feature Summary

• Supports AES3, IEC-60958, S/PDIF, and EIAJ CP1201 input standards
• Includes a 7:1 S/PDIF input multiplexer for multi-source selection
• Features on-chip channel status and user data buffer memories
• Provides differential cable receiver input

Audio Special Purpose Applications

• Audio/Video receivers
• CD-R and DVD receivers
• Microwave speakers
• Digital mixing consoles
• Set-top boxes

Audio Special Purpose Procurement Notes

Verify the specific package variant against the datasheet ordering information. The suffix 'ZR' indicates a Tape and Reel container format. Confirm that the required operating temperature range matches the Commercial grade specifications (0°C to +70°C) as defined in the product documentation.

Audio Special Purpose Selection Notes

Select this component for systems requiring reception of professional or consumer digital audio formats. Ensure the host system provides either an SPI or I²C interface for register configuration. Verify that the power supply architecture can support separate VA+ and VL+ rails if jitter-sensitive applications require isolated analog supplies.

Audio Special Purpose Part Context

This part belongs to the CS8415A series of digital audio receivers. The CS8415A-CSZR specifically denotes the commercial grade version housed in a 28-SOIC package and supplied in a tape and reel configuration. Other variants in the family include different packaging options such as TSSOP.

Audio Special Purpose Replacement Considerations

Direct pin-compatible alternatives within the same manufacturer's portfolio include the CS8415A-CZZR (TSSOP package) or the CS8415A-CSR (SOIC package). Cross-vendor replacements may require significant schematic redesign due to differing pinouts and control interfaces.
