CS8416K-CSZ

Audio Special Purpose Overview

The CS8416K-CSZ is a monolithic CMOS digital audio interface receiver manufactured by Cirrus Logic Inc. It receives and decodes one of eight stereo pairs of digital audio data according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 standards. The device features an 8:2 S/PDIF input multiplexer, low-jitter clock recovery, and flexible serial digital output ports. It operates with a +3.3V analog supply (VA), +3.3V digital supply (VD), and a +3.3V or +5.0V digital interface supply (VL). The component supports sample frequencies from 32 kHz to 192 kHz and is housed in a 28-SOIC package.

Audio Special Purpose Feature Summary

• Integrated 8:2 S/PDIF input multiplexer for flexible source selection
• Low-jitter clock recovery mechanism for clean signal reconstruction
• Supports both SPI and I²C control port interfaces

Audio Special Purpose Applications

• A/V receivers
• CD-R and DVD receivers
• Multimedia speakers
• Digital mixing consoles
• Effects processors

Audio Special Purpose Procurement Notes

Verify the specific suffix 'CSZ' against the manufacturer's current ordering information to confirm package type and qualification status. Confirm that the commercial grade operating temperature range (-10°C to +70°C) meets system requirements. Check for end-of-life notices as this component family may have discontinued variants.

Audio Special Purpose Selection Notes

Select this model for applications requiring robust decoding of professional and consumer digital audio formats. Ensure the design accommodates the separate VA, VD, and VL power supplies. Verify that the 28-SOIC package dimensions fit the PCB layout constraints. Consider the need for external PLL filter components to optimize jitter performance.
