CDCVF857RTBT Equivalent & Substitute Parts

Part Overview

The CDCVF857RTBT is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications requiring differential SSTL-2 signaling. This device operates at a maximum frequency of 220MHz with a 2:11 input-to-output ratio and is housed in a 40-VFQFN exposed pad package.

The CDCVF857RTBT carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and field replacement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCVF857RTBT is determined by strict equivalence across the following critical parameters:

• Maximum frequency: 220MHz
• Input and output signaling standard: SSTL-2 differential
• Input-to-output ratio: 2:11
• Supply voltage range: 2.3V ~ 2.7V
• Operating temperature range: -40°C ~ 85°C
• Package type: 40-VFQFN exposed pad
• Mounting configuration: Surface mount

The CDCVF857RHAT meets all specified electrical and mechanical parameters and qualifies as a parametric equivalent substitute for the CDCVF857RTBT.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF857RHAT is the recommended substitute for the obsolete CDCVF857RTBT. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications and physical packaging. The CDCVF857RHAT carries Active product status, ensuring ongoing availability and manufacturing support.

Both parts comply with ROHS3 requirements and carry identical moisture sensitivity ratings. Selection between these parts should be based on component availability and supply chain requirements, as electrical and mechanical compatibility is fully established.

Frequently Asked Questions (FAQ)

Q: Can the CDCVF857RHAT be used as a direct replacement for the CDCVF857RTBT?

A: Yes. The CDCVF857RHAT is a parametric equivalent with identical electrical specifications, signaling standards, frequency range, supply voltage, operating temperature, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The CDCVF857RTBT is classified as Obsolete, while the CDCVF857RHAT maintains Active product status. Both parts are functionally equivalent and meet all specified parameters.

Q: Are there any packaging or mounting differences?

A: No. Both parts use the 40-VFQFN exposed pad package with surface mount configuration. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CDCVF857RTBT and CDCVF857RHAT are ROHS3 compliant with identical moisture sensitivity levels (MSL 3, 168 hours).

Q: What are the critical parameters for substitution eligibility?

A: Substitution is based on matching frequency (220MHz), signaling standard (SSTL-2 differential input and output), input-to-output ratio (2:11), supply voltage range (2.3V ~ 2.7V), operating temperature range (-40°C ~ 85°C), and package type (40-VFQFN exposed pad).
