SI5338N-B06022-GM

Overview

The SI5338N-B06022-GM is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with 0 ppm precision using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for LVDS/LVPECL/CML. Core supply voltage ranges from 1.71 V to 3.63 V (1.8 V, 2.5 V, or 3.3 V). Typical operating current is 45 mA. Phase jitter is typically 0.7 ps RMS. The component is housed in a 24-lead QFN package.

Feature Summary

• I2C/SMBus programmable interface for flexible configuration
• MultiSynth technology enabling zero ppm frequency accuracy on all outputs
• Supports up to four differential outputs or eight single-ended outputs
• Independent output voltage selection: 1.5 V, 1.8 V, 2.5 V, or 3.3 V per driver

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm factory programming parameters. The 'GM' suffix indicates tape and reel packaging. Confirm that the I2C pull-up voltage requirements align with the system design, particularly if operating below 2.5 V.

Selection Notes

Select this model when independent frequency synthesis across four channels is required. Ensure the target output format (LVDS, LVPECL, etc.) and voltage levels match the load requirements. Verify that the input reference source (crystal, CMOS, or differential) falls within the supported frequency ranges specified in the datasheet.

Part Context

This component belongs to the Si5338 family of low-jitter clock generators. It replaces multiple discrete crystal oscillators by providing any-frequency synthesis. The device integrates a PLL and MultiSynth dividers to generate precise clock signals from a single reference input.
