SI5338M-B10099-GMR

Overview

The SI5338M-B10099-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports any-frequency generation with zero ppm precision and features low phase jitter of 0.7 ps RMS typical. The device accepts various input references including differential clocks up to 710 MHz and single-ended inputs up to 200 MHz. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL, or CML formats with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V per driver. It operates on a single core supply of 1.8, 2.5, or 3.3 V within a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Independently configurable outputs support multiple signal formats (LVPECL/LVDS, HCSL, CMOS, SSTL/HSTL) with individual voltage supplies.

Applications

• Ethernet switch/router timing
• PCIe Gen1/2/3/4 clocking
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix B10099 against the manufacturer's current documentation to confirm the exact frequency plan and pinout configuration. Ensure compatibility with I2C/SMBus programming interfaces using ClockBuilder Pro software. Check for moisture sensitivity levels and recommended reflow soldering profiles prior to assembly.

Selection Notes

Select this component when designing systems requiring independent clock frequencies with high precision and low jitter across multiple outputs. Consider the available output formats (LVDS, LVPECL, CMOS, etc.) and their respective voltage requirements. Verify that the input reference source matches the supported frequency ranges and signal types defined in the electrical specifications.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. The family utilizes patented MultiSynth technology to replace multiple discrete oscillators. Variations within the family differ primarily by the pre-programmed frequency plans stored in the internal NVM, while sharing the same core architecture and package.

Replacement Considerations

Direct replacements must be from the Si5338 family with compatible frequency plans. Verify that alternative SKUs support the required output formats and jitter specifications. Ensure the replacement part maintains the same QFN-24 footprint and I2C interface compatibility.
