SI5338A-B01343-GMR

Overview

The SI5338A-B01343-GMR is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with any frequency up to 710 MHz and zero ppm precision. The device supports flexible input references, including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz). Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, or HSTL formats with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, typical operating current of 45 mA, and a typical RMS phase jitter of 0.7 ps.

Feature Summary

• MultiSynth technology enables independent, glitchless frequency synthesis on four outputs with 0 ppm accuracy.

• Configurable spread spectrum generation with adjustable deviation and modulation rates.

Applications

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

Procurement Notes

Verify the specific ordering suffix B01343 against the manufacturer's official documentation to confirm the programmed frequency plan and output configuration. Ensure compatibility with the required I2C interface levels and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the target output signal format (LVDS, LVPECL, etc.) and frequency range fall within the specified limits for each driver. Confirm that the available reference input matches the supported frequency ranges.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. It replaces discrete crystal oscillators and buffers in complex digital systems. The device integrates programmable PLLs and output drivers into a compact 4x4 mm QFN-24 package.

Replacement Considerations

Direct replacements must match the 24-QFN package and support similar I2C programming capabilities. Verify pinout compatibility and ensure the substitute device meets the required jitter specifications and output drive strengths for the application.
