CS4223-DSZ Equivalent & Substitute Parts

Part Overview

The CS4223-DSZ is a stereo audio codec interface manufactured by Cirrus Logic Inc., designed for 24-bit serial audio applications. This component integrates dual ADCs and DACs with Sigma-Delta conversion architecture, operating across analog and digital supply voltages of 4.75V to 5.25V. The device is classified as obsolete, necessitating identification of functionally compatible alternatives for ongoing system support and new designs requiring equivalent audio interface capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS4223-DSZ is determined by the following critical parameters:

• Resolution and Channel Configuration: 24-bit resolution with 2 ADCs and 2 DACs (stereo audio)
• Data Interface Type: Serial interface for audio data transmission
• Conversion Architecture: Sigma-Delta modulation
• Supply Voltage Compatibility: Analog supply 4.75V ~ 5.25V; Digital supply 4.75V ~ 5.25V
• Operating Temperature Range: -40°C ~ 85°C
• Mounting and Package: Surface mount technology

The CS4271-DZZ qualifies as a substitute based on matching resolution, channel count, serial data interface, Sigma-Delta architecture, and operating temperature range. Package differences (28-TSSOP vs. 28-SSOP) and enhanced dynamic range specifications do not preclude substitution when PCB layout accommodates the alternative package footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the CS4223-DSZ and CS4271-DZZ are classified as obsolete products. Selection between these components should be based on:

Package Footprint Compatibility: The CS4271-DZZ uses a 28-TSSOP package (0.173" width) compared to the CS4223-DSZ 28-SSOP package (0.209" width). PCB layout and routing must accommodate the selected package geometry.

Digital Supply Voltage Range: The CS4271-DZZ supports a wider digital supply range (3.1V ~ 5.25V) versus the CS4223-DSZ (4.75V ~ 5.25V). Systems operating at lower digital supply voltages require the CS4271-DZZ.

Dynamic Range Performance: The CS4271-DZZ provides enhanced dynamic range specifications (108 dB ADC, 114 dB DAC) compared to the CS4223-DSZ (105 dB both). Applications requiring superior audio fidelity benefit from this improvement.

Compliance and Certification: The CS4271-DZZ carries RoHS3 compliance and REACH unaffected status. Both components share identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the CS4271-DZZ directly replace the CS4223-DSZ without design modifications?

A: Functional replacement is possible due to matching resolution, channel configuration, serial interface, and operating temperature range. However, package footprint differences require PCB layout evaluation. The 28-TSSOP package is narrower than the 28-SSOP, necessitating verification of pin spacing compatibility with existing PCB designs.

Q: What are the key differences between these two audio codec parts?

A: Primary differences include package type (28-TSSOP vs. 28-SSOP), digital supply voltage range (3.1V ~ 5.25V vs. 4.75V ~ 5.25V), and dynamic range specifications (108/114 dB vs. 105/105 dB). Core audio interface functionality remains equivalent.

Q: Are there any compliance or certification differences?

A: The CS4271-DZZ includes RoHS3 compliance and REACH unaffected status documentation. Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the moisture sensitivity level for these components?

A: Both the CS4223-DSZ and CS4271-DZZ carry MSL 3 rating with a 168-hour floor life requirement. Standard moisture control procedures apply during storage and handling.

Q: Can the CS4271-DZZ operate at lower digital supply voltages than the CS4223-DSZ?

A: Yes. The CS4271-DZZ supports digital supply voltages as low as 3.1V, while the CS4223-DSZ requires a minimum of 4.75V. This expanded range provides flexibility for multi-voltage system designs.
