SI5338C-B05034-GM

Overview

The SI5338C-B05034-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports flexible input references, including differential inputs up to 710 MHz and single-ended CMOS inputs up to 200 MHz. Output formats include LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with frequencies ranging from 0.16 MHz to 710 MHz depending on the format. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V, consuming approximately 45 mA. The component features low phase jitter of 0.7 ps RMS typical and is housed in a 24-lead QFN package.

Feature Summary

• I2C/SMBus programmable with ClockBuilder Pro software
• Four independent outputs supporting any frequency and signal format
• Low phase jitter: 0.7 ps RMS typical
• Zero ppm frequency accuracy via MultiSynth technology

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 ordering suffix against the manufacturer's current datasheet revision to confirm pinout compatibility and factory programming parameters. Ensure I2C pull-up voltages align with the system bus requirements, as register adjustments may be necessary for voltages below 2.5 V. Confirm moisture sensitivity levels and reflow soldering profiles during assembly planning.

Selection Notes

Select this model when independent frequency synthesis across four outputs is required without external oscillators. Verify that the target output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Ensure the input reference source falls within the supported frequency ranges for the chosen input type (differential vs. single-ended).

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The 'C' designation typically indicates specific factory-programmed frequency and configuration parameters, while 'GM' denotes the 24-lead QFN package. The device replaces multiple discrete crystal oscillators, reducing board space and power consumption in complex digital systems.

Replacement Considerations

Direct replacements must maintain the 24-QFN footprint and I2C interface. Verify that substitute components support the same maximum input frequency (710 MHz) and output format flexibility. Check if alternative parts offer comparable jitter performance and zero ppm accuracy for PCIe or Ethernet applications.
