SI5338A-B04406-GM

Overview

The SI5338A-B04406-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS and accepts various input references including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz). Configuration is managed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs
• Supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL output formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input options: crystal, CMOS, SSTL/HSTL, or differential signals

Applications

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

Procurement Notes

Verify the specific ordering suffix B04406 against the manufacturer's official documentation to confirm the programmed frequency plan and configuration settings. Ensure the package type matches the required PCB land pattern for the 24-lead QFN form factor.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source. Verify that the target output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Confirm input signal compatibility with the available reference types.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. It replaces discrete oscillators in complex digital systems. The 'GM' suffix indicates the 24-lead QFN package variant.
