SI5338C-B04171-GM

Overview

The SI5338C-B04171-GM is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended formats including LVDS, LVPECL, HCSL, CMOS, SSTL, and HSTL. Maximum input frequencies reach 710 MHz for differential inputs and 200 MHz for single-ended sources. Output frequencies range from 0.16 to 710 MHz depending on the selected format. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V within a 4x4 mm QFN-24 package.

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 typical.
• Highly configurable outputs support LVDS, LVPECL, HCSL, CMOS, SSTL, and HSTL formats.
• Flexible input reference options include external crystals (8-30 MHz), CMOS (5-200 MHz), and differential signals (up to 710 MHz).

Applications

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

Procurement Notes

Verify the specific factory-programmed configuration associated with the B04171 suffix against the target design requirements. Confirm that the required output frequencies and signal formats match the programmed parameters, as the device is not field-reprogrammable without specialized tools. Ensure the I2C interface voltage levels are compatible with the host controller.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the desired output formats (LVDS, LVPECL, etc.) align with the available driver configurations. Check that the input source matches the supported frequency ranges for the chosen pin type. Consider the thermal characteristics and operating temperature range (-40 to +85 °C) for the application environment.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' in the model number typically denotes a specific output frequency range limitation compared to other variants in the series. The 'GM' suffix indicates the QFN-24 package type. These devices are designed to replace multiple discrete crystal oscillators in complex digital systems.

Replacement Considerations

Direct replacements must be sought within the Si5338 family with matching output configurations. Verify that alternative part numbers support the same output formats and frequency ranges. Ensure compatibility with existing programming software such as ClockBuilder Pro if reconfiguration is needed.
