CS5364-CQZ

ADCs/DACs - Special Purpose Overview

The CS5364-CQZ is a 4-channel, 24-bit audio analog-to-digital converter (ADC) utilizing an advanced multi-bit delta-sigma architecture. It supports sample rates up to 216 kHz per channel with a typical dynamic range of 114 dB and -105 dB THD+N. The device integrates low-latency digital filtering, eliminating the need for external anti-aliasing filters. It features differential analog inputs, separate logic supplies for control and serial ports (1.8 V to 5 V), and an on-chip oscillator driver. The component operates in Commercial grade (-40°C to +85°C) within a 48-pin LQFP package.

ADCs/DACs - Special Purpose Feature Summary

• 4-Channel 24-Bit Conversion: Performs sampling, A/D conversion, and anti-alias filtering simultaneously across four channels.
• High Performance: Achieves 114 dB dynamic range and -105 dB THD+N at standard audio sample rates.
• Flexible Interface: Supports Left-Justified, I²S, and high-speed TDM formats with auto-detect speed in slave mode.
• Integrated Clocking: Includes an on-chip crystal oscillator driver and supports master or slave system clock operation.

ADCs/DACs - Special Purpose Applications

• A/V receivers
• Digital mixing consoles
• Multi-channel recorders
• Outboard converters
• Automotive audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix '-CQZ' confirms the Commercial temperature grade (-40°C to +85°C). Confirm the 48-pin LQFP package dimensions match the target PCB footprint. Ensure power supply decoupling capacitors are placed close to VA, VD, VLS, and VLC pins as specified in the typical connection diagram to maintain signal integrity.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring four independent audio channels with high dynamic range. The CS5364-CQZ is suitable for designs needing integrated anti-alias filtering and flexible digital interface options like TDM. Verify that the host processor supports the required serial data formats and control interfaces (I²C or SPI). Check if the on-chip oscillator driver meets the system clock frequency requirements.

ADCs/DACs - Special Purpose Part Context

The CS5364-CQZ belongs to the Cirrus Logic CS5364 series of high-performance audio ADCs. It is footprint compatible with the 8-channel CS5368, allowing for design scalability. The 'CQZ' suffix denotes the Commercial temperature range and LQFP packaging, distinguishing it from Automotive grades or other package variants within the same functional family.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5368 is noted as footprint compatible. For direct pin-compatible replacements within the same series, verify specific ordering information for alternative suffixes such as CS5364-DQZ (Automotive grade) or different package types if available in public datasheets.
