PL620-88OC Equivalent & Substitute Parts

Part Overview

The PL620-88OC is a clock buffer IC manufactured by Microchip Technology, designed to operate at 65MHz with LVPECL output. This device features a 1:1 input-to-output ratio with differential output capability and operates across a supply voltage range of 2.25V to 3.63V. The component is housed in a 16-TSSOP surface mount package and is ROHS3 compliant with MSL Level 1 rating.

The PL620-88OC has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL620-88OC is determined by the following critical parameters:

• Output Configuration: LVPECL differential output capability
• Frequency Range: Maximum operating frequency of 65MHz or higher
• Input Type: Crystal or clock input compatibility
• Supply Voltage Compatibility: Overlapping or compatible voltage ranges
• Package Type: Surface mount configuration
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The 83PN156DKILF qualifies as a substitute based on these criteria. While it operates at a higher maximum frequency (156.25MHz) and includes integrated PLL functionality, it maintains LVPECL differential output, supports both crystal and clock inputs, operates within compatible supply voltage ranges, and meets identical compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The 83PN156DKILF is an active product from Renesas Electronics Corporation and represents a viable substitute for the obsolete PL620-88OC. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The 83PN156DKILF offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and higher maximum frequency capability (156.25MHz versus 65MHz). The supply voltage ranges overlap sufficiently for most applications. The primary design consideration is the package change from 16-TSSOP to 10-VQFN, which requires PCB layout modification. The 83PN156DKILF includes integrated PLL functionality and accepts both clock and crystal inputs, providing additional flexibility compared to the crystal-only input of the PL620-88OC.

The MSL rating difference (Level 1 versus Level 3) affects moisture handling during storage and assembly; Level 3 requires controlled humidity storage for 168 hours maximum before reflow.

Frequently Asked Questions (FAQ)

Q: Can the 83PN156DKILF directly replace the PL620-88OC without design changes?

A: The 83PN156DKILF provides functional equivalence in output type, input compatibility, and differential signaling. However, the package change from 16-TSSOP to 10-VQFN requires PCB layout redesign. Pin assignments and footprints differ between these packages.

Q: What are the supply voltage compatibility considerations?

A: The PL620-88OC operates at 2.25V to 3.63V, while the 83PN156DKILF operates at 2.375V to 3.465V. The overlap range is 2.375V to 3.465V. Designs operating at the extremes of the original specification may require voltage adjustment.

Q: Does the higher frequency rating of the 83PN156DKILF affect compatibility?

A: Higher maximum frequency capability does not prevent operation at lower frequencies. The 83PN156DKILF can operate at 65MHz and below without performance degradation. The extended frequency range provides design margin and future flexibility.

Q: What is the impact of the MSL rating difference?

A: The PL620-88OC has MSL Level 1 (unlimited shelf life), while the 83PN156DKILF has MSL Level 3 (168-hour limit after moisture exposure). The 83PN156DKILF requires controlled humidity storage and must be reflowed within 168 hours of bag opening. This affects supply chain handling and assembly scheduling.

Q: Are there input configuration differences?

A: The PL620-88OC accepts crystal input only. The 83PN156DKILF accepts both clock and crystal inputs, with integrated PLL support. Designs using crystal input remain compatible; clock input capability provides additional application flexibility.

Q: How does the extended temperature range affect system design?

A: The 83PN156DKILF operates from -40°C to 85°C compared to 0°C to 70°C for the PL620-88OC. This extended range supports wider environmental conditions and industrial applications without performance compromise in standard temperature ranges.
