SI5338C-B04190-GM

Overview

The SI5338C-B04190-GM is a programmable quad clock generator from Skyworks Solutions, 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 with a core supply of 1.8 V, 2.5 V, or 3.3 V and accepts inputs up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential outputs, and an operating temperature range of –40 °C to +85 °C.

Feature Summary

• I2C/SMBus programmable interface for flexible configuration
• Low phase jitter of 0.7 ps RMS typical
• Independent glitchless frequency adjustment in 1 ppm steps
• Supports spread spectrum modulation on any output

Applications

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

Procurement Notes

Verify the specific suffix B04190 against the manufacturer's current ordering guide to confirm factory-programmed frequencies and pinout configurations. Ensure compatibility with I2C bus voltage levels (1.71 V to 3.63 V) and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when zero-ppm frequency accuracy is required across multiple independent clocks. Validate that the target output formats (LVPECL, LVDS, etc.) match the load conditions and supply voltages supported by the Si5338 family. Use ClockBuilder Pro software to generate the necessary register map for the desired frequency plan.

Part Context

This part belongs to the Si5338 family of low-jitter clock generators. The 'C' designation typically indicates a specific factory-programmed variant within the series, distinct from user-programmable versions like the SI5338A or SI5338Q. It shares the same 24-QFN package and core architecture as other members of the family.

Replacement Considerations

Direct replacements must be verified via the Skyworks Cross Reference Tool. Other Si5338 variants may require reprogramming if they are not pre-configured with identical frequencies.
