SI5338C-B05602-GM

Overview

The Skyworks SI5338C-B05602-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency with zero ppm precision on four independent outputs. It operates from a single core supply of 1.8, 2.5, or 3.3 V and accepts differential inputs up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, glitchless frequency adjustment in 1 ppm steps, and independent phase offset control under 20 ps. Outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats across varying voltage levels.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Flexible input reference options including external crystals (8-30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Independent output voltage configuration per driver at 1.5, 1.8, 2.5, or 3.3 V supporting multiple signal formats.
• Glitchless frequency adjustments via independent increment/decrement features and programmable spread spectrum.

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 against the manufacturer's current documentation to confirm package type and shipping configuration. Confirm that the I2C pull-up voltage requirements align with the system design, particularly if operating below 2.5 V. Ensure ESD handling protocols are followed as the device is sensitive to electrostatic discharge.

Selection Notes

Select this component when zero ppm frequency accuracy and independent output formatting are required. Verify that the input source matches the supported frequency ranges for the chosen interface mode. Consider the thermal resistance characteristics and ensure adequate PCB land patterns are designed for the 24-QFN package to maintain optimal heat dissipation.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. It is designed to replace multiple discrete crystal oscillators or function as a frequency translator. The device integrates an I2C/SMBus interface for configuration and supports programming via ClockBuilder Pro software.

Replacement Considerations

Direct replacements within the same series include variants such as SI5338A, SI5338Q, and SI5338J. These parts share identical pinouts and core functionality but may differ in pre-programmed frequencies or specific output configurations. Verify register compatibility before substitution.
