SI5338D-B09540-GMR

Overview

The SI5338D-B09540-GMR is an I2C-programmable quad clock generator from Skyworks Solutions. It synthesizes any frequency on four output drivers using MultiSynth technology, achieving zero ppm precision. The device supports a core supply of 1.8, 2.5, or 3.3 V and operates within a temperature range of –40 to +85 °C. It features low phase jitter of 0.7 ps RMS typical and accepts differential inputs up to 710 MHz. Outputs include LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference supporting external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz)
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

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 ordering suffix B09540 against the manufacturer's current documentation to confirm the programmed configuration. Ensure the I2C pull-up voltage requirements are met for standard mode compatibility. Check for moisture sensitivity handling instructions during storage and assembly.

Selection Notes

Select this component when zero ppm frequency accuracy is required across multiple outputs. Verify that the desired output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the specified ranges. Confirm that the input source matches the supported types, such as differential clocks up to 710 MHz.

Part Context

This part belongs to the Si5338 family of high-performance, low-jitter clock generators. The family utilizes patented MultiSynth technology to replace multiple crystal oscillators. The device is housed in a space-saving 4 x 4 mm QFN package suitable for dense PCB layouts.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers. Generic replacements may not support the same MultiSynth programming capabilities or jitter specifications.
