PI6CV855-02LE Equivalent & Substitute Parts

Part Overview

The PI6CV855-02LE is a PLL Clock Driver IC manufactured by Diodes Incorporated, designed for clock distribution and timing applications requiring SSTL-2 differential signaling. This component operates at a maximum frequency of 200MHz with a 1:5 input-to-output ratio and is housed in a 28-TSSOP surface mount package. The part is currently classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI6CV855-02LE is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 28-TSSOP (0.173", 4.40mm Width)
• Input / Output Signaling: SSTL-2 / SSTL-2
• Ratio - Input:Output: 1:5
• Differential - Input:Output: Yes / Yes
• Voltage - Supply: 2.3V ~ 2.7V
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount

Allowable Variation:

• Frequency - Max: Substitute must meet or exceed the application requirement; the PI6CV855-02LE operates at 200MHz maximum

The CDCV855PW from Texas Instruments meets all mandatory matching parameters and is therefore classified as a parametric equivalent. The maximum frequency specification of 180MHz for the CDCV855PW represents the only parameter variance and must be evaluated against specific application frequency requirements.

Parameter Comparison

Engineering Selection Recommendations

The CDCV855PW is a parametric equivalent suitable for direct substitution in applications where the maximum operating frequency does not exceed 180MHz. Both components maintain identical electrical characteristics for supply voltage, signaling standards, and differential input/output configuration, ensuring functional compatibility at the circuit level.

The PI6CV855-02LE is classified as Obsolete, while the CDCV855PW carries a Not For New Designs status. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between these parts should be based on application frequency requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can the CDCV855PW replace the PI6CV855-02LE in all applications?

A: The CDCV855PW is a parametric equivalent for applications operating at frequencies up to 180MHz. If your system requires operation above 180MHz, the CDCV855PW does not meet the frequency specification. Verify your application's maximum operating frequency before substitution.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the PI6CV855-02LE and CDCV855PW use the 28-TSSOP package with identical dimensions of 0.173" × 4.40mm width. PCB layout and footprints are directly compatible.

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

A: The PI6CV855-02LE is Obsolete, indicating it is no longer manufactured. The CDCV855PW is marked Not For New Designs, meaning it remains available but is not recommended for new product development. Both statuses indicate limited long-term availability.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both components operate with identical supply voltage ranges of 2.3V to 2.7V and identical operating temperature ranges of 0°C to 70°C.

Q: Do both parts support SSTL-2 differential signaling?

A: Yes. Both the PI6CV855-02LE and CDCV855PW feature SSTL-2 differential input and output signaling with a 1:5 input-to-output ratio and PLL with bypass capability.
