Renesas 552R-01LN Clock Generator Equivalent & Substitute Parts

Part Overview

The Renesas 552R-01LN is a Clock Generator and Multiplexer IC designed for 200MHz applications in a 20-SSOP surface mount package. This component generates clock signals with a 1:8 input-to-output ratio and supports both clock and crystal inputs with CMOS output. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The Renesas 5P83908NDGK qualifies as a functional substitute for the 552R-01LN based on the following critical parameters:

Matching Parameters:

• Manufacturer: Renesas Electronics Corporation (same source)
• Frequency - Max: 200 MHz (identical specification)
• Ratio - Input:Output: 1:8 (identical fanout configuration)
• Input Type: Crystal (compatible input source)
• Output Type: LVCMOS (compatible logic family)
• Number of Circuits: 1 (identical circuit count)
• Mounting Type: Surface Mount (same assembly method)

Functional Equivalence Basis: Both parts perform clock distribution and buffering with identical frequency and fanout specifications. The 5P83908NDGK is classified as a Fanout Buffer (Distribution) IC, which provides the same 1:8 clock multiplication and distribution function as the original Clock Generator, Multiplexer design.

Parameter Comparison

Engineering Selection Recommendations

The 5P83908NDGK is the recommended substitute for the obsolete 552R-01LN based on product lifecycle status and compliance certifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming equivalent regulatory standing.

The substitute part supports an extended operating temperature range (-40°C ~ 105°C) compared to the original part (0°C ~ 70°C), providing greater thermal flexibility for diverse application environments. The substitute part also supports multiple supply voltage options (1.8V, 2.5V, 3.3V) versus the original part's 3V ~ 5.5V range, enabling compatibility with modern low-power system designs.

Package differences exist between the parts: the original uses 20-SSOP while the substitute uses 20-VFQFN with exposed pad. PCB layout modifications are required to accommodate the different package footprint and thermal management characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5P83908NDGK directly replace the 552R-01LN without circuit modifications?

A: The parts share identical frequency and fanout specifications (200 MHz, 1:8 ratio), but package differences require PCB layout redesign. The 20-SSOP footprint differs from the 20-VFQFN footprint, necessitating new PCB artwork. Supply voltage ranges differ; verify your system voltage compatibility with the substitute part's supported levels (1.8V, 2.5V, 3.3V).

Q: What are the key differences in electrical specifications?

A: The substitute part supports lower supply voltages (1.8V minimum versus 3V minimum) and operates across a wider temperature range (-40°C to 105°C versus 0°C to 70°C). Output logic families differ slightly: CMOS versus LVCMOS. Both support crystal input and deliver identical 200 MHz maximum frequency with 1:8 fanout.

Q: Why is the package different between these parts?

A: The original 552R-01LN uses 20-SSOP packaging, while the 5P83908NDGK uses 20-VFQFN with exposed pad. Both are 20-pin surface mount packages suitable for automated assembly, but the footprint dimensions and thermal characteristics differ. The VFQFN package includes an exposed pad for improved thermal dissipation.

Q: Is the substitute part RoHS compliant?

A: Yes, the 5P83908NDGK carries ROHS3 compliance certification. The original 552R-01LN RoHS status is not specified in available documentation.

Q: What is the availability status of each part?

A: The 552R-01LN is classified as obsolete with limited remaining inventory (1423 pcs reported). The 5P83908NDGK is in active production status with current inventory availability (632 pcs reported), ensuring ongoing supply for new designs and production requirements.
