SI5338C-B04726-GM

Overview

The SI5338C-B04726-GM 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, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Low phase jitter of 0.7 ps RMS typical for high-performance timing applications.
• Highly-configurable output drivers supporting up to four differential or eight single-ended outputs.
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V.

Applications

• PCIe Gen1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory programming parameters associated with the B04726 suffix against the official datasheet ordering information section. Confirm that the required input reference frequencies and output signal formats match the pre-programmed configuration stored in the device's NVM.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package. Ensure the target application supports the available output formats (LVPECL, LVDS, HCSL, etc.) and voltage levels. Verify that the I2C bus voltage compatibility aligns with the system design, particularly if operating below 2.5 V.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. The 'C' designation typically indicates a specific performance grade or feature set within the series, while the alphanumeric suffix denotes factory-programmed clock parameters.

Replacement Considerations

Direct replacements must be sought from the Si5338 family variants (e.g., SI5338A, SI5338B) with matching factory programming. Generic clock generators cannot substitute this part due to the unique MultiSynth architecture and pre-defined frequency synthesis requirements.
