ADF5610BCCZ Equivalent & Substitute Parts

Part Overview

The ADF5610BCCZ is an Integer-N/Fractional-N VCO IC manufactured by Analog Devices Inc., designed for clock and timing applications with a maximum frequency of 14.6GHz. This component operates as a phase-locked loop (PLL) with integrated divider and multiplier functionality, supporting dual supply voltage ranges (3.1V–4.6V and 4.75V–5.25V) and a wide operating temperature range of -40°C to 85°C.

The ADF5610BCCZ is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADF5610BCCZ is determined by the following critical parameters:

• Frequency Range: Maximum operating frequency must meet or exceed 14.6GHz
• PLL Architecture: Must include integrated phase-locked loop functionality
• Divider/Multiplier Support: Both divider and multiplier circuits required
• Supply Voltage Compatibility: Operating voltage ranges must overlap with or encompass the original specification
• Package Type: Surface mount 48-pin LGA package with exposed pad
• Operating Temperature Range: Must support -40°C to 85°C minimum
• Moisture Sensitivity: MSL rating of 3 or better

The ADF4372BCCZ qualifies as a substitute based on these parameters. While it operates at a higher maximum frequency (16GHz) and supports an extended upper operating temperature (105°C), it maintains compatibility with the core functional requirements and package specifications of the ADF5610BCCZ.

Engineering Selection Recommendations

The ADF4372BCCZ is the manufacturer-recommended substitute for the obsolete ADF5610BCCZ. Selection of this substitute is supported by the following factors:

• Product Status: The ADF4372BCCZ maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete ADF5610BCCZ.
• Compliance & Certifications: Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, maintaining regulatory consistency. The ADF4372BCCZ is RoHS3 compliant and REACH unaffected.
• Functional Compatibility: The ADF4372BCCZ exceeds the frequency specification of the original part (16GHz vs. 14.6GHz) and extends the operating temperature range to 105°C, providing enhanced performance margins.
• Package Compatibility: Both components use 48-pin LGA surface mount packages with exposed pads, maintaining PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ADF4372BCCZ directly replace the ADF5610BCCZ without design modifications?

A: The ADF4372BCCZ is functionally compatible with the ADF5610BCCZ for applications operating within the original part's frequency range (up to 14.6GHz) and temperature range (-40°C to 85°C). Both components use 48-pin LGA packages with exposed pads. However, the ADF4372BCCZ operates at a higher maximum frequency (16GHz) and supports an extended temperature range (up to 105°C). Verification of pin-level compatibility and register programming requirements is necessary before implementation.

Q: What are the key differences in supply voltage between these parts?

A: The ADF5610BCCZ supports dual supply ranges: 3.1V–4.6V and 4.75V–5.25V. The ADF4372BCCZ operates on a single supply range of 3.15V–3.45V. Applications using the 4.75V–5.25V supply range of the original part require voltage regulation or redesign to accommodate the ADF4372BCCZ.

Q: Are the package types identical?

A: Both components use 48-pin LGA packages with exposed pads in a 7×7mm footprint. The ADF5610BCCZ uses VFLGA packaging, while the ADF4372BCCZ uses TFLGA packaging. These designations indicate different thermal and electrical characteristics but maintain the same physical footprint and pin count, supporting PCB layout compatibility.

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

A: Both the ADF5610BCCZ and ADF4372BCCZ have an MSL rating of 3 with a 168-hour floor life. This classification requires controlled storage conditions and handling procedures consistent with IPC-A-610 standards.

Q: Is the ADF4372BCCZ suitable for applications requiring the 4.75V–5.25V supply voltage of the original part?

A: No. The ADF4372BCCZ operates only on 3.15V–3.45V supply voltage. Applications requiring the higher supply voltage range must either implement voltage regulation to step down to the ADF4372BCCZ operating range or identify alternative substitute components.
