SI5338M-B05237-GMR

Overview

The SI5338M-B05237-GMR is a 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 differential and single-ended outputs with independent voltage configurations (1.5V to 3.3V). It operates on a single core supply of 1.8V, 2.5V, or 3.3V, drawing a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, a typical RMS jitter of 0.7 ps, and operation within a temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance.
• Flexible output drivers configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL, or CML formats.
• Independent phase adjustment (<20 ps steps) and glitchless frequency adjustments in 1 ppm steps.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin assignments and configuration settings. Ensure compatibility with I2C/SMBus programming interfaces and required supply voltages during procurement planning.

Selection Notes

Select this component when low-jitter synthesis (0.7 ps typ) and flexible output formatting are required. Confirm that the application utilizes the supported input reference frequencies (up to 710 MHz differential) and fits within the 4x4 mm QFN-24 package constraints.

Part Context

This part belongs to the Si5338 family of high-performance, low-jitter clock generators. The series is designed to replace multiple crystal oscillators or function as frequency translators in complex digital systems requiring precise timing synchronization across various interfaces.

Replacement Considerations

Consult the official datasheet for verified substitute part numbers within the Si5338 family. Ensure any replacement maintains identical output driver configurations, jitter specifications, and I2C programming compatibility.
