SI5340A-A-GM

Overview

The Skyworks SI5340A-A-GM is a programmable clock generator from the Si5340 Rev D family, housed in a 44-pin QFN package. It features four independent outputs capable of generating any frequency up to 1.028 GHz with 0 ppm synthesis error using MultiSynth technology. The device integrates a fully contained phase-locked loop (PLL) and supports input frequencies up to 750 MHz via XA/XB or IN0-IN2 pins. Key electrical parameters include a supply voltage range of 1.71 V to 3.47 V, operating temperatures from -40°C to +85°C, and output formats including CML, HCSL, LVCMOS, LVDS, and LVPECL.

Feature Summary

• Generates any combination of output frequencies from any input frequency with 0 ppm error
• Integrates a low-jitter PLL with fully on-chip loop filter
• Supports factory preprogrammed non-volatile memory (NVM) for known power-up configurations
• Configurable via I2C or SPI serial interfaces

Applications

• High-performance networking equipment requiring precise timing
• Telecommunications infrastructure systems
• Data center server platforms needing flexible clock trees

Procurement Notes

Verify the specific ordering suffix 'A' against the manufacturer's current product selection guide to confirm availability status and exact revision details. Confirm that the required NVM configuration matches the factory-programmed part number specifications.

Selection Notes

Select this component when a compact 4-output solution is required. Ensure the design utilizes ClockBuilder Pro software for optimal divider configuration. Verify that the application requires the specific output count and frequency range supported by the Si5340 variant rather than the 10-output Si5341.

Part Context

This part belongs to the Si5341/40 Rev D family reference manual. It shares architectural similarities with the Si5341 but is distinguished by having four fractional dividers and four outputs compared to the Si5341's five dividers and ten outputs.

Replacement Considerations
