Engineering Selection Recommendations

All three parts—SI5332C-D-AM2, SI5332A-D-AM2, and SI5332B-D-AM2—are Active products from Skyworks Solutions Inc. with identical electrical specifications and package configurations. Each part maintains ROHS3 compliance and carries the same ECCN and HTSUS classifications, confirming regulatory equivalence.

Selection between these parts should be based on availability and supply chain requirements. Current inventory levels are:

SI5332C-D-AM2: 1129 units
SI5332A-D-AM2: 1145 units
SI5332B-D-AM2: 1601 units

All three parts are suitable for direct substitution in applications requiring a 333.33MHz dual-output clock generator with PLL and bypass functionality in a 40-VFQFN package.

Frequently Asked Questions (FAQ)

Q: Can SI5332A-D-AM2 or SI5332B-D-AM2 be used as direct replacements for SI5332C-D-AM2?

A: Yes. All three parts share identical electrical and mechanical specifications, including frequency range, output circuit count, signal standards, supply voltage, operating temperature, and package configuration. They are parametric equivalents suitable for direct substitution.

Q: Are there any differences in the 40-VFQFN package between these parts?

A: No. All three parts use the identical 40-QFN (6x6) package with exposed pad configuration. PCB layout and thermal management considerations remain unchanged across substitutions.

Q: Do all three parts support the same input and output signal standards?

A: Yes. Each part accepts Clock, Crystal, and LVCMOS inputs, and provides HCSL, LVCMOS, LVDS, and LVPECL outputs. Signal compatibility is maintained across all three variants.

Q: What is the significance of the part number suffix (A, B, C)?

A: The suffix indicates different revisions within the SI5332 base product family. Despite these designations, the A, B, and C variants maintain identical parametric specifications for the -D-AM2 configuration, making them interchangeable for applications requiring these electrical and mechanical characteristics.

Q: Are moisture sensitivity and storage requirements the same for all three parts?

A: Yes. All three parts carry MSL Level 2 with a 1-year floor life rating, requiring identical handling and storage protocols.

Q: Which part should be selected based on availability?

A: Selection should prioritize current inventory levels and supply chain lead times. SI5332B-D-AM2 currently has the highest inventory (1601 units), followed by SI5332A-D-AM2 (1145 units) and SI5332C-D-AM2 (1129 units). All are suitable for immediate deployment.
