SI5338F-B04073-GM

Overview

The SI5338F-B04073-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency with zero ppm precision on four independent output drivers. It operates within a core supply voltage range of 1.71 V to 3.63 V and supports frequencies up to 710 MHz for differential outputs (LVPECL/LVDS/CML) and 200 MHz for CMOS. The device features low phase jitter of 0.7 ps RMS typical, configurable spread spectrum modulation, and independent phase adjustment. It is housed in a compact 4 x 4 mm QFN-24 package.

Feature Summary

• MultiSynth™ Technology: Generates four independent clocks with true zero ppm frequency accuracy.
• Flexible Output Drivers: Supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels (1.5V, 1.8V, 2.5V, or 3.3V).
• Low Jitter Performance: Typical random jitter of 0.7 ps RMS; compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Glitchless Frequency Adjustment: Independent frequency increment/decrement feature allows adjustments in 1 ppm steps without glitches.

Applications

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

Procurement Notes

Verify the specific ordering suffix B04073 against the manufacturer's current datasheet to confirm the exact pre-programmed frequency configuration and pinout variant. Ensure I2C pull-up voltages are compatible with the selected VDDI2C level, as register modifications may be required for bus voltages below 2.5 V.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with high precision. Ensure the input reference signal matches the supported formats (Crystal, CMOS, Differential, etc.) and that the output load capacitance requirements for the chosen signal format (e.g., CMOS vs LVDS) are met by the system design.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'F' designation typically indicates a specific output driver configuration or frequency range variant within the series, while 'B04073' denotes the factory-programmed frequency plan. The '-GM' suffix indicates the tape and reel packaging option.

Replacement Considerations

Direct replacements must match the 24-QFN package and support similar output configurations. Other Si5338 variants (e.g., Si5338Q, Si5338M) offer different output combinations or jitter profiles but require reprogramming via ClockBuilder Pro software to replicate the specific frequency plan of the B04073 variant.
