SI5338N-B06108-GMR

Overview

The Si5338N-B06108-GMR is a quad clock generator utilizing MultiSynth technology for any-frequency synthesis. It features four independent output drivers configurable as differential or single-ended, supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with supply voltages of 1.5, 1.8, 2.5, or 3.3 V. The device accepts external crystals (8–30 MHz), CMOS, SSTL/HSTL, or differential inputs up to 710 MHz. Key electrical parameters include a typical core supply current of 45 mA at 1.8 V, phase jitter of 0.7 ps RMS typ, and operation from –40 to +85 °C in a 24-lead QFN package.

Feature Summary

• Low phase jitter of 0.7 ps RMS typical
• Zero ppm frequency accuracy on all outputs
• Independent output voltage selection: 1.5, 1.8, 2.5, or 3.3 V
• Flexible input reference support up to 710 MHz

Applications

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

Procurement Notes

Verify the ordering suffix 'GMR' corresponds to the specific reel quantity and tape configuration defined in the official Skyworks Solutions ordering guide. Confirm that the 'N' designation aligns with the required RoHS compliance status for the target assembly process. Cross-reference the full part number against the latest datasheet revision to ensure no functional changes have been introduced since the document date.

Selection Notes

Select this component when independent frequency synthesis with zero ppm precision is required across four outputs. Ensure the target application supports the I2C/SMBus programming interface via ClockBuilder Pro software. Verify that the input clock source matches one of the supported formats: external crystal, CMOS, SSTL/HSTL, or differential signals within the specified frequency ranges.

Part Context

This model belongs to the Si533x family of programmable clock generators. It shares the MultiSynth architecture with other devices in the series but offers four output drivers compared to fewer in smaller variants. The 'B06108' code indicates a specific factory configuration or pre-programmed register set, while 'GMR' denotes the packaging format.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement requires verification of pin compatibility, electrical specifications, and software configuration files using Skyworks ClockBuilder Pro tools.
