CS8415A-CSZ

Audio Special Purpose Overview

The CS8415A-CSZ is a monolithic CMOS digital audio interface receiver designed to receive and decode one of seven channels of audio data according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 standards. It features a 7:1 input multiplexer for selecting the active channel and supports sample frequencies from 8 kHz to 96 kHz. The device includes a low-jitter clock recovery mechanism and provides flexible serial digital output. It operates with a +5.0 V analog supply (VA+) and a +3.3 V or +5.0 V digital interface supply (VL+). The component is housed in a 28-SOIC package.

Audio Special Purpose Feature Summary

• Low-jitter clock recovery mechanism
• Flexible 3-wire serial digital output port
• On-chip channel status and user data buffers accessible via SPI or I²C

Audio Special Purpose Applications

• Audio/Video receivers
• DVD and CD-R receivers
• Microwave speakers
• Digital mixing consoles
• Automotive audio systems

Audio Special Purpose Procurement Notes

The CS8415A-CSZ is listed as Obsolete/Discontinued by Cirrus Logic. Distributors may list it as limited stock or end-of-life. Verify specific ordering suffixes against manufacturer documentation to confirm package type (SOIC-28) and temperature grade (Commercial).

Audio Special Purpose Selection Notes

Select the CS8415A-CSZ for applications requiring commercial temperature range operation (0°C to +70°C) and a SOIC-28 footprint. Ensure the system design accommodates the required +5.0 V analog supply and compatible digital logic levels. Note that industrial temperature variants use different suffixes (e.g., -IZ, -IZZ).

Audio Special Purpose Part Context

The CS8415A belongs to Cirrus Logic's family of 96 kHz digital audio interface receivers. This series includes variants such as the CS8415A-CZZ (TSSOP package) and industrial grade options like CS8415A-IZZ. The CS8415A-CSZ specifically identifies the commercial grade device packaged in a standard 28-pin Small Outline Integrated Circuit (SOIC) format.

Audio Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same package and grade include the CS8415A-CSZR (tape and reel version of the same part). For different packages, the CS8415A-CZZ serves as a TSSOP equivalent. Industrial grade requirements necessitate switching to the CS8415A-IZZ or CS8415A-IZZR variants.
