PCK2002PDP Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The PCK2002PDP is a Clock Fanout Buffer (Distribution) IC manufactured by NXP USA Inc., designed for 1:4 clock distribution at 533 MHz with LVTTL input and output levels. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The part operates within a 3V to 3.6V supply range and is housed in an 8-TSSOP package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCK2002PDP is determined by the following critical parameters:

• Functional Configuration: 1:4 fanout buffer topology with single circuit
• Signal Interface: LVTTL input and output compatibility
• Package Type: 8-TSSOP surface mount package
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Range: Compatibility within 2.3V to 3.6V envelope
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The CDCV304PWR from Texas Instruments meets these substitution criteria. While the maximum frequency specification differs (200 MHz versus 533 MHz), the CDCV304PWR maintains functional equivalence for applications operating within its frequency capability. The substitute part shares identical signal interface specifications, package configuration, temperature range, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The CDCV304PWR is suitable as a substitute for the obsolete PCK2002PDP based on the following factors:

• Product Status: The CDCV304PWR maintains active product status with established supply chain availability, addressing the obsolescence of the original part.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring continued regulatory alignment.
• Functional Equivalence: Identical 1:4 fanout buffer configuration, LVTTL signal interface, and operating temperature range provide direct functional compatibility.
• Supply Voltage Compatibility: The substitute part's 2.3V to 3.6V supply range encompasses the original part's 3V to 3.6V specification.
• Package Compatibility: Both parts use 8-TSSOP surface mount packages. Physical dimensions differ slightly (0.118" versus 0.173" width), requiring PCB layout verification for new designs.

Frequently Asked Questions (FAQ)

Q: Can the CDCV304PWR directly replace the PCK2002PDP in existing designs?

A: The CDCV304PWR provides functional substitution for applications operating at clock frequencies within its 200 MHz maximum specification. The 1:4 fanout configuration, LVTTL signal interface, and operating temperature range are identical. PCB layout must accommodate the slightly larger package width (0.173" versus 0.118").

Q: What is the primary limitation of the CDCV304PWR as a substitute?

A: The maximum frequency specification is 200 MHz compared to the PCK2002PDP's 533 MHz. Applications requiring clock distribution above 200 MHz require alternative evaluation.

Q: Are there any supply voltage considerations when substituting?

A: The CDCV304PWR operates across 2.3V to 3.6V, providing broader supply voltage tolerance than the PCK2002PDP's 3V to 3.6V range. Both parts are compatible with standard 3.3V supply systems.

Q: Do both parts share the same pinout configuration?

A: Both parts use 8-TSSOP packages with identical functional pin assignments for 1:4 fanout buffer operation. Physical package dimensions differ, requiring PCB footprint verification.

Q: What is the moisture sensitivity level for both parts?

A: Both the PCK2002PDP and CDCV304PWR carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage and handling.

Q: Are there regulatory compliance differences between the parts?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No regulatory compliance differences exist between the original and substitute part.
