CDCVF857RHAR PLL Clock Driver IC Equivalent & Substitute Parts

Part Overview

The CDCVF857RHAR is a PLL Clock Driver IC manufactured by Texas Instruments, designed for high-speed clock distribution applications with a maximum frequency of 220MHz. This component features differential SSTL-2 input and output signaling, making it suitable for low-voltage, high-speed digital systems. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement planning. Active substitute parts maintain identical electrical and mechanical specifications while offering current product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDCVF857RHAR is determined by strict equivalence across the following critical parameters:

• Frequency capability: 220MHz maximum
• Signal interface: SSTL-2 differential input and output
• Multiplication ratio: 2:11 input-to-output
• Supply voltage range: 2.3V ~ 2.7V
• Package form factor: 40-VFQFN Exposed Pad (6x6mm)
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: ROHS3, REACH Unaffected

The CDCVF857RHAT qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and packaging format, with the substitute available in active production status and Tape & Reel packaging.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF857RHAT is the direct equivalent substitute for the CDCVF857RHAR. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The CDCVF857RHAT is preferred for new designs and ongoing procurement due to its active product status, ensuring long-term availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The packaging difference (Tape & Reel versus bulk) does not affect functional compatibility and is determined by procurement volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can CDCVF857RHAT directly replace CDCVF857RHAR in existing designs?

A: Yes. The CDCVF857RHAT is electrically and mechanically identical to the CDCVF857RHAR. Pin configuration, signal levels, frequency response, and supply voltage requirements are equivalent. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The CDCVF857RHAR is classified as obsolete, indicating Texas Instruments has discontinued active manufacturing and support. The CDCVF857RHAT maintains active product status, ensuring continued availability, manufacturing consistency, and technical support from the manufacturer.

Q: Are there packaging compatibility considerations?

A: The CDCVF857RHAR is supplied in bulk packaging, while the CDCVF857RHAT is supplied in Tape & Reel format. Both use the same 40-VQFN (6x6mm) package. Tape & Reel packaging is standard for automated assembly processes and does not affect component functionality or performance.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the CDCVF857RHAR and CDCVF857RHAT are ROHS3 compliant and REACH Unaffected. Moisture Sensitivity Level is identical at MSL 3 (168 Hours) for both parts.

Q: What are the critical parameters for substitution verification?

A: Substitution is valid when the following parameters match: maximum frequency (220MHz), signal interface type (SSTL-2 differential), input-to-output ratio (2:11), supply voltage range (2.3V ~ 2.7V), operating temperature range (-40°C ~ 85°C), and package form factor (40-VFQFN Exposed Pad).
