SI5338C-B05559-GM

Overview

The Skyworks SI5338C-B05559-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V with a typical current consumption of 45 mA. It features low phase jitter of 0.7 ps RMS typ, flexible input references up to 710 MHz, and glitchless frequency adjustment via I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports highly configurable output drivers for up to four differential outputs, eight single-ended outputs, or combinations thereof.
• Low phase jitter performance of 0.7 ps RMS typical value.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (5–710 MHz).

Applications

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

Procurement Notes

Verify the specific ordering suffix B05559 against the manufacturer's official documentation to confirm pre-programmed configuration data or specific variant characteristics. Ensure compatibility with the required I²C address and voltage levels during procurement planning.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single package. Verify that the target output formats (LVPECL, LVDS, etc.) and frequencies fall within the supported ranges defined in the electrical specifications table. Confirm power supply requirements match the available system rails.

Part Context

This part belongs to the Si5338 family of I²C-programmable any-frequency, any-output quad clock generators. It is designed to replace multiple discrete crystal oscillators or frequency translators in high-performance digital systems.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Generic replacements may not support the same MultiSynth architecture or jitter performance metrics.
