SI5338N-B05552-GMR

Overview

The SI5338N-B05552-GMR is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with 0 ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is managed via an I2C/SMBus interface.

Feature Summary

• Four independent output drivers supporting any frequency synthesis up to 710 MHz
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options including external crystals (8-30 MHz), CMOS, and differential inputs
• I2C/SMBus compatible programming interface for configuration

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS applications
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout and functional variations. Ensure compatibility with the required I2C bus voltage levels and check for moisture sensitivity classification prior to surface mount assembly.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Confirm that the target output signal formats (LVPECL, LVDS, etc.) match the available driver configurations. Validate that the input reference frequency falls within the supported range for the chosen input type.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The series is designed to replace multiple discrete crystal oscillators in complex digital systems. It offers space-saving integration in a 4x4 mm QFN package while maintaining low power consumption and wide temperature operation.

Replacement Considerations

Direct replacements must be verified through official Skyworks substitution guides. Cross-model comparisons should account for differences in output drive strength, jitter specifications, and programming software compatibility.
