CDCV855IPWR PLL Clock Driver Equivalent & Substitute Parts

Part Overview

The CDCV855IPWR is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications requiring differential SSTL-2 input and output signaling. This device operates at a maximum frequency of 180MHz with a 1:5 input-to-output ratio and is housed in a 28-TSSOP surface mount package.

The CDCV855IPWR carries a "Not For New Designs" product status, indicating that Texas Instruments has discontinued active development and support for this component. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements, maintenance applications, and design updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCV855IPWR is determined by the following critical parameters:

• Package Compatibility: Identical 28-TSSOP (0.173", 4.40mm Width) surface mount package
• Signaling Standards: SSTL-2 differential input and output capability
• Supply Voltage Range: 2.3V ~ 2.7V operating range
• Operating Temperature: -40°C ~ 85°C range
• PLL Architecture: PLL with Bypass functionality
• Number of Circuits: Single circuit configuration
• Compliance: ROHS3 Compliant, REACH Unaffected status

The CDCVF855PWR qualifies as a direct substitute based on these parameters. While the CDCVF855PWR exhibits a higher maximum frequency (220MHz versus 180MHz) and a different input-to-output ratio (2:5 versus 1:5), these differences represent enhanced capabilities that maintain backward compatibility with applications designed for the CDCV855IPWR within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF855PWR is the designated substitute for the CDCV855IPWR based on the following engineering criteria:

Product Status Alignment: The CDCVF855PWR maintains Active product status with Texas Instruments, ensuring continued availability, technical support, and compliance updates. This contrasts with the CDCV855IPWR's "Not For New Designs" classification, which indicates end-of-life status and reduced manufacturer support.

Regulatory Compliance: Both components maintain ROHS3 Compliance and REACH Unaffected status, ensuring compatibility with current environmental and regulatory requirements across global markets.

Electrical and Mechanical Compatibility: The CDCVF855PWR shares identical package geometry, supply voltage range, operating temperature range, and signaling standards with the CDCV855IPWR. The enhanced frequency capability (220MHz) and modified input-to-output ratio (2:5) represent performance improvements that do not compromise backward compatibility for applications operating within the original design specifications.

Inventory and Supply Chain: The CDCVF855PWR is available in Tape & Reel packaging with confirmed inventory, supporting production requirements and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the CDCVF855PWR directly replace the CDCV855IPWR in existing designs?

A: Yes. The CDCVF855PWR is electrically and mechanically compatible with the CDCV855IPWR. Both components share identical package geometry (28-TSSOP), supply voltage range (2.3V ~ 2.7V), operating temperature range (-40°C ~ 85°C), and SSTL-2 differential signaling standards. Pin-to-pin compatibility is maintained.

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

A: The CDCVF855PWR operates at a maximum frequency of 220MHz compared to the CDCV855IPWR's 180MHz. The input-to-output ratio differs (2:5 versus 1:5). The CDCVF855PWR maintains Active product status, while the CDCV855IPWR is classified as "Not For New Designs."

Q: Are there any packaging differences?

A: Both components use the 28-TSSOP (0.173", 4.40mm Width) surface mount package. The CDCVF855PWR is supplied in Tape & Reel packaging, which is standard for production quantities.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CDCV855IPWR and CDCVF855PWR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Why should I transition from CDCV855IPWR to CDCVF855PWR?

A: The CDCV855IPWR carries "Not For New Designs" status, indicating discontinued active development. The CDCVF855PWR's Active status ensures ongoing manufacturer support, technical documentation updates, and supply chain availability for current and future production requirements.
