SI5338A-B01392-GMR

Overview

The SI5338A-B01392-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device accepts flexible inputs: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential signals (5–710 MHz). Outputs reach up to 710 MHz for LVPECL/LVDS/CML, 350 MHz for SSTL/HSTL, 250 MHz for HCSL, and 200 MHz for CMOS. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, 45 mA core supply current, and operation from a 1.8 V, 2.5 V, or 3.3 V core supply.

Feature Summary

• I2C/SMBus programmable with zero ppm frequency accuracy
• Low phase jitter of 0.7 ps RMS typical
• Independent glitchless frequency adjustment in 1 ppm steps
• Configurable spread spectrum (SSC) with 0.5% to 5.0% deviation

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS
• Ethernet switch/router and 1 GbE/10 GbE
• FPGA and processor clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Ensure I2C pull-up voltages match the system design requirements for standard or fast mode compatibility.

Selection Notes

Select this component when independent frequency synthesis across four outputs is required. Verify that the target output format (LVPECL, LVDS, etc.) falls within the supported frequency ranges. Ensure the input reference source matches the compatible voltage levels and frequencies specified in the electrical characteristics.
