CS2000P-CZZ Equivalent & Substitute Parts

Part Overview

The CS2000P-CZZ is a Fractional N Synthesizer IC manufactured by Cirrus Logic Inc., designed for clock and timing applications with a maximum frequency of 75MHz. This device integrates a phase-locked loop (PLL) with 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 packaged in a 10-TFSOP, 10-MSOP surface mount configuration and is currently classified as Last Time Buy, indicating limited future availability. Identifying equivalent and substitute parts is necessary to ensure design continuity and supply chain resilience.

Substitute Part Grouping Explanation

Substitution of the CS2000P-CZZ is determined by strict equivalence across the following critical parameters:

Functional Type: Fractional N Synthesizer with integrated PLL
Maximum Frequency: 75MHz
Supply Voltage Range: 3.1V ~ 4.6V
Operating Temperature Range: -10°C ~ 70°C
Package Configuration: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)
Input/Output Signal Type: Clock/Clock
Circuit Count: 1
Divider/Multiplier Capability: Yes/Yes

Engineering Selection Recommendations

Primary Substitutes (Active Status)

CS2000P-DZZ and CS2100P-DZZ are recommended as primary substitutes due to their Active product status, ensuring continued availability and long-term supply chain stability. Both parts maintain full electrical and mechanical equivalence to the CS2000P-CZZ while offering superior lifecycle support.

Secondary Substitutes (Last Time Buy Status)

CS2000CP-CZZ and CS2100CP-CZZ are functionally equivalent but carry Last Time Buy designation, indicating limited future availability. These parts are suitable for immediate replacement needs but should not be selected for new long-term designs.

Compliance Considerations

All substitute parts maintain ROHS3 compliance or equivalent RoHS certification, ensuring regulatory alignment. Moisture Sensitivity Level (MSL) 2 with 1-year shelf life applies uniformly across all parts, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can CS2000P-DZZ be used as a direct replacement for CS2000P-CZZ?

A: Yes. CS2000P-DZZ is a parametric equivalent with identical electrical specifications, supply voltage, operating temperature range, and package configuration. The primary difference is product status: CS2000P-DZZ is Active while CS2000P-CZZ is Last Time Buy.

Q: What is the difference between CS2000 and CS2100 base product numbers?

A: Both CS2000 and CS2100 series parts are Fractional N Synthesizers with identical functional parameters as specified in this document. Substitution between these series is valid based on the matching electrical and mechanical criteria listed.

Q: Are packaging differences between tube and other packaging types significant for substitution?

A: Packaging type (tube) does not affect electrical or mechanical compatibility. All parts listed use the same 10-TFSOP, 10-MSOP surface mount package with 0.118" width and 3.00mm height. Packaging differences relate only to quantity and handling during procurement.

Q: Does the -CZZ or -DZZ suffix affect substitution eligibility?

A: No. The suffix designates internal Cirrus Logic product variants but does not alter the electrical specifications, frequency range, supply voltage, operating temperature, or package configuration. Substitution is valid across suffix variants when all other parameters match.

Q: What is the significance of Last Time Buy versus Active status?

A: Last Time Buy indicates the manufacturer will discontinue production after current inventory is depleted. Active status indicates ongoing production and availability. For new designs, Active parts are preferred; Last Time Buy parts are suitable only for near-term production or replacement of existing designs.

Q: Are all substitute parts ROHS3 compliant?

A: Five of six substitute parts are ROHS3 compliant. CS210005-CZZ carries RoHS Compliant designation without the "3" specification. Both certifications meet regulatory requirements; ROHS3 represents the most current standard.
