SI5338N-B05936-GMR

Overview

The SI5338N-B05936-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Input frequencies range from 5 MHz to 710 MHz. Core supply voltage options are 1.8 V, 2.5 V, or 3.3 V. Typical phase jitter is 0.7 ps RMS. Operating temperature spans -40 °C to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typical
• High precision synthesis allows true zero ppm frequency accuracy on all outputs
• Flexible input reference supporting external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz)

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Broadcast video/audio timing
• Processor and FPGA clocking
• MSAN/DSLAM/PON

Procurement Notes

Verify the specific N suffix configuration against the official Skyworks ordering guide. Confirm that the B05936 code matches the required frequency plan and output format. Check for moisture sensitivity handling requirements during storage and assembly. Ensure I2C pull-up voltages align with the selected core supply voltage.

Selection Notes

Select this component when independent frequency generation across four outputs is required. Verify that the target output formats (LVPECL, LVDS, etc.) match the application load. Ensure the input reference source falls within the supported frequency ranges. Consider the 0.7 ps RMS jitter specification for high-speed serial link compliance.
