CS2000CP-CZZR Equivalent & Substitute Parts

Part Overview

The CS2000CP-CZZR is a Fractional N Synthesizer IC manufactured by Cirrus Logic Inc., designed for clock and timing applications with a maximum frequency of 75MHz. This component integrates a Phase-Locked Loop (PLL) with programmable divider and multiplier functionality, operating from a 3.1V to 4.6V supply across an operating temperature range of -10°C to 70°C. The part is housed in a 10-TFSOP/10-MSOP surface mount package with 0.118" width and 3.00mm pitch.

The CS2000CP-CZZR carries a Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring fractional N synthesis functionality.

Engineering Selection Recommendations

CS2000P-DZZR: This substitute maintains full parametric equivalence to the CS2000CP-CZZR with identical electrical and mechanical specifications. The primary distinction is packaging format (Tape & Reel vs. standard packaging) and active product status. This part is suitable for direct replacement in production environments requiring continuous supply.

CS210005-CZZR: This part provides parametric equivalence across all critical electrical and functional parameters. It carries RoHS Compliant status (versus ROHS3 Compliant on the main part). This substitute is appropriate for applications where RoHS compliance is required.

CS2100P-DZZR: This substitute offers full parametric equivalence with active product status and Tape & Reel packaging. It maintains ROHS3 compliance and identical electrical specifications. This part is recommended for high-volume production applications requiring reliable long-term supply.

All three substitute parts are manufactured by Cirrus Logic Inc. and maintain identical functional architecture, electrical performance, and package compatibility with the CS2000CP-CZZR.

Frequently Asked Questions (FAQ)

Q: Can CS2000P-DZZR be used as a direct replacement for CS2000CP-CZZR?

A: Yes. Both parts are parametrically equivalent across all electrical, functional, and mechanical specifications. The difference in packaging format (Tape & Reel vs. standard) does not affect electrical compatibility or performance.

Q: What is the difference between CS210005-CZZR and the main part?

A: CS210005-CZZR is parametrically equivalent to CS2000CP-CZZR across all critical specifications. The base product number differs (CS210005 vs. CS2000), but electrical performance, frequency range, supply voltage, operating temperature, and package type are identical.

Q: Why is CS2000CP-CZZR marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Substitute parts with Active status (CS2000P-DZZR, CS210005-CZZR, CS2100P-DZZR) ensure continued availability for new designs and production requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. CS2000P-DZZR and CS2100P-DZZR carry ROHS3 Compliant status. CS210005-CZZR carries RoHS Compliant status. All meet environmental compliance requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) packaging is a supply format only and does not alter electrical characteristics, frequency response, or functional performance of the IC.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts maintain identical pin configuration, package dimensions (10-TFSOP/10-MSOP with 0.118" width and 3.00mm pitch), and electrical specifications. No PCB redesign or firmware modification is required.
