SI5338D-B05172-GMR

Overview

The SI5338D-B05172-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent clocks with zero ppm accuracy and low jitter of 0.7 ps RMS typical. The device supports flexible input references including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats across various supply voltages. It operates on a single core supply of 1.8, 2.5, or 3.3 V within an industrial temperature range of –40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm precision.
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly-configurable outputs support differential or single-ended formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL.
• I2C/SMBus compatible interface allows glitchless frequency adjustments in 1 ppm steps and independent phase alignment.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure I2C pull-up voltage compatibility with the target system bus.

Selection Notes

Select this component when independent frequency synthesis on multiple outputs is required without integer multiples. Verify that the desired output format (LVDS, LVPECL, etc.) and frequency ranges fall within the specified limits for each driver. Ensure the input reference source matches the supported types, such as differential or single-ended signals.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators from Skyworks Solutions. The family utilizes patented MultiSynth architecture to replace multiple discrete oscillators. The device integrates a PLL and synthesis stages into a compact 4x4 mm QFN-24 package suitable for space-constrained designs.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the Si5338 series. Verify electrical parameters such as jitter performance and output drive strength when substituting with other programmable clock generators.
