SI5338M-B05701-GM

Overview

The SI5338M-B05701-GM 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 formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device accepts flexible inputs such as external crystals (8–30 MHz), CMOS (up to 200 MHz), or differential clocks (up to 710 MHz). Key electrical parameters include a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, a typical operating current of 45 mA, and a phase jitter specification of 0.7 ps RMS. It operates within a temperature range of –40 °C to +85 °C.

Feature Summary

• Low power MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• High precision synthesis allows true zero ppm frequency accuracy on all outputs.
• Independent frequency increment/decrement feature enables glitchless frequency adjustments in 1 ppm steps.
• Highly configurable spread spectrum (SSC) on any output with frequency from 5 to 350 MHz and spread from 0.5 to 5.0%.

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Processor and FPGA clocking
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix 'B05701' against the manufacturer's official documentation to confirm factory-programmed frequency settings. Ensure compatibility with I2C/SMBus interfaces and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single package. Consider the required output voltage levels (1.5, 1.8, 2.5, or 3.3 V) and signal formats (LVPECL, LVDS, etc.) to ensure driver compatibility. Verify input reference constraints, such as crystal load capacitance or differential input swing limits.
