SI5338N-B05168-GMR

Overview

The SI5338N-B05168-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates on 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 performed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential signals.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs
• Supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL output formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input options: external crystal (8-30 MHz), CMOS (5-200 MHz), or differential (5-710 MHz)

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout configuration and factory programming settings. 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 desired output signal formats (LVDS, LVPECL, etc.) match the available driver configurations. Verify that the input reference frequency falls within the supported ranges for the chosen input type.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'N' suffix typically denotes a specific pinout or functional variant within the series, while 'GMR' indicates tape and reel packaging. It replaces discrete oscillators in high-density designs.

Replacement Considerations

Direct replacements must be verified against the official Skyworks substitution guide. Ensure any substitute maintains the same QFN-24 package dimensions and pin assignments to avoid PCB redesign.
