CS2000P-CZZR Equivalent & Substitute Parts

Part Overview

The CS2000P-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 integrated divider and multiplier functionality, operating from a 3.1V to 4.6V supply in a 10-MSOP surface mount package.

The CS2000P-CZZR is currently in 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 new production runs or design revisions.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status)

CS2000P-DZZR, CS210005-CZZR, and CS2100P-DZZR are all actively manufactured alternatives with identical electrical and mechanical specifications to the CS2000P-CZZR. All three substitutes maintain ROHS3 compliance (or equivalent RoHS compliance) and MSL Level 2 ratings, ensuring compatibility with standard manufacturing and storage protocols.

Packaging Consideration

CS2000P-DZZR and CS2100P-DZZR are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. CS210005-CZZR does not specify packaging format in the provided data but maintains identical package geometry and electrical specifications.

Supply Chain Availability

Current inventory levels across all substitutes range from 844 to 1,033 pieces, providing adequate supply for production planning. The transition from Last Time Buy (CS2000P-CZZR) to Active status across all substitutes ensures long-term design support and component availability.

Frequently Asked Questions (FAQ)

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

A: Yes. CS2000P-DZZR is electrically and mechanically identical to CS2000P-CZZR, with the primary difference being active product status versus Last Time Buy status. Both share identical supply voltage (3.1V–4.6V), frequency range (75MHz maximum), package geometry (10-MSOP), and operating temperature range (-10°C to 70°C).

Q: What is the difference between CS2000P-DZZR and CS2100P-DZZR?

A: Both parts are functionally equivalent Fractional N Synthesizers with identical electrical specifications. The primary distinction is the base product number designation (CS2000 versus CS2100), which reflects internal Cirrus Logic product line categorization. Electrical performance, package type, and compliance certifications are identical.

Q: Is CS210005-CZZR compatible with existing PCB designs for CS2000P-CZZR?

A: Yes. CS210005-CZZR maintains the same 10-MSOP package geometry, pinout, supply voltage range, frequency specifications, and operating temperature range as the original part. The base product number change (CS210005 versus CS2000) does not affect functional compatibility.

Q: Are all substitutes RoHS compliant?

A: Yes. CS2000P-DZZR and CS2100P-DZZR are ROHS3 compliant. CS210005-CZZR is RoHS compliant. All three meet environmental regulatory requirements for electronic component manufacturing and assembly.

Q: What is the MSL rating, and does it affect component handling?

A: All parts carry MSL Level 2 (1 Year) rating, indicating moisture sensitivity. Components must be stored in controlled humidity environments and used within one year of packaging opening. Standard moisture barrier packaging and desiccant storage are required.
