SI5338F-A-GM

Overview

The SI5338F-A-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential and single-ended outputs with independent voltage configurations (1.5V, 1.8V, 2.5V, or 3.3V). The device operates on a single core supply of 1.8V, 2.5V, or 3.3V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, zero ppm frequency accuracy, and flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz).
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V.
• Low phase jitter of 0.7 ps RMS typ.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant
• Ethernet switch/router
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's ordering guide to confirm pinout and configuration details. Ensure I2C pull-up voltages are compatible with the selected core supply voltage. Check for moisture sensitivity levels and recommended reflow profiles during assembly.

Selection Notes

Select this model for applications requiring up to four independent clock outputs with varying frequencies and signal formats. Ensure the required output frequency range aligns with the specific driver type (e.g., LVPECL/LVDS up to 710 MHz, CMOS up to 200 MHz). Verify that the input reference source matches one of the supported types.

Part Context

The SI5338F-A-GM belongs to the Si5338 family of quad clock generators. This series is designed to replace multiple discrete oscillators in high-performance systems. The 'F' variant typically denotes specific frequency capabilities or output configurations within the broader Si5338 product line.

Replacement Considerations

Direct replacements within the Si5338 family include SI5338A-B-GM or SI5338Q-B-GMR, depending on the required output frequency range and format. Verify pin compatibility and register settings when substituting.
