SI5338C-B05617-GM

Overview

The SI5338C-B05617-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency up to 710 MHz with zero ppm precision on four independent outputs. The device supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. It operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, output frequencies ranging from 0.16 MHz to 710 MHz, and a typical RMS phase jitter of 0.7 ps.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Supports flexible input references: external crystals (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential inputs (5-710 MHz).
• Features low phase jitter of 0.7 ps RMS typ and glitchless frequency adjustments via independent increment/decrement pins.
• Configurable spread spectrum (SSC) allows any frequency from 5 to 350 MHz with spread from 0.5 to 5.0%.

Applications

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

Procurement Notes

Verify the specific ordering suffix B05617 against the manufacturer's official documentation to confirm the exact pre-programmed frequency plan and output configuration. Ensure the I2C pull-up voltage requirements are met if operating below 2.5 V by writing to register 27. Confirm package availability and moisture sensitivity handling procedures prior to assembly.

Selection Notes

Select this component when designing systems requiring four independent clock signals with varying frequencies and output formats. Ensure the required output voltage levels (1.5, 1.8, 2.5, or 3.3 V) match the target loads. Verify that the input reference source falls within the supported frequency ranges for the chosen input type (differential vs. single-ended).

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It is housed in a space-saving 4 x 4 mm, 24-lead QFN package. The device is designed to replace multiple discrete crystal oscillators or operate as a frequency translator in high-performance digital systems.

Replacement Considerations

Consult the Skyworks Solutions cross-reference guide for verified pin-compatible or functionally equivalent alternatives within the Si533x series. Ensure any substitute maintains the required MultiSynth capabilities and output format support.
