SI5338A-B04407-GMR

Overview

The SI5338A-B04407-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency up to 710 MHz with zero ppm accuracy on four independent outputs. The device supports LVDS and LVPECL output formats, operates from a single 1.8 V, 2.5 V, or 3.3 V core supply, and draws 45 mA typical current. It features low phase jitter of 9 ps RMS, I2C/SMBus control, and is housed in a 24-lead QFN package.

Feature Summary

• I2C-programmable synthesis supporting any frequency up to 710 MHz
• Four differential outputs configurable for LVDS or LVPECL formats
• Low phase jitter specification of 9 ps RMS
• Single core supply operation at 1.8 V, 2.5 V, or 3.3 V

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm factory packaging details and revision status. Cross-reference the part number with official Skyworks Solutions databases to ensure compatibility with required design-in software tools such as ClockBuilder Pro.

Selection Notes

Select this component when differential LVDS or LVPECL outputs are required for frequencies up to 710 MHz. Ensure the application utilizes an I2C interface for configuration and requires glitchless frequency adjustments. Verify that the target system accommodates the 24-QFN package dimensions and thermal requirements.

Part Context

This model belongs to the Si5338 family of high-performance clock generators. It replaces multiple discrete crystal oscillators by providing independent frequency synthesis on all four drivers. The device integrates flexible input references and spread spectrum capabilities within a compact footprint suitable for dense PCB layouts.

Replacement Considerations

Consult the official Skyworks cross-reference guide for verified substitutes. Generic replacements may not support the specific B04407 configuration or MultiSynth architecture.
