SI5338A-B05317-GMR

Overview

The SI5338A-B05317-GMR is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Maximum output frequencies reach 710 MHz for differential formats and 200 MHz for CMOS. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, consuming typically 45 mA. Key electrical parameters include a typical phase jitter of 0.7 ps RMS and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).

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. Ensure compatibility with I2C/SMBus interface requirements for system integration. Confirm that the selected variant meets the thermal and voltage constraints for the intended application environment.

Selection Notes

Select this component when low jitter and flexible frequency synthesis are required for high-speed serial interfaces. Verify that the required output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the specified operational limits. Consider the power supply voltage availability and the need for independent output voltage levels when designing the board layout.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The family is designed to replace multiple crystal oscillators in complex digital systems. The Si5338 series offers space-saving QFN packaging and supports glitchless frequency adjustments via independent increment/decrement features.

Replacement Considerations

Consult the official Skyworks Solutions substitution guide for verified compatible alternatives. Ensure that any replacement maintains the same pinout, electrical characteristics, and programming interface compatibility.
