SI5338A-B07234-GMR

Overview

The SI5338A-B07234-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent clocks with zero ppm accuracy via an I2C interface. The device supports input frequencies up to 710 MHz and generates outputs ranging from 0.16 MHz to 710 MHz depending on the selected format (LVPECL, LVDS, HCSL, CMOS, SSTL/HSTL). Key electrical parameters include a typical core supply current of 45 mA, a phase jitter of 0.7 ps RMS, and operation within a temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth technology enables independent frequency synthesis on four output drivers with true zero ppm precision.
• Supports flexible input references including external crystals (8-30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Features low phase jitter of 0.7 ps RMS typ and configurable spread spectrum modulation.
• Programmable via I2C/SMBus interface with support for glitchless frequency adjustments.

Applications

• PCIe Gen 1/2/3/4 Common Clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking solutions
• Broadcast video/audio timing applications

Procurement Notes

Verify the specific ordering suffix B07234 against the manufacturer's official documentation to confirm factory-programmed frequency settings. Ensure compatibility with the required I2C bus voltage levels (1.71 V to 3.63 V) and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when independent any-frequency synthesis is required for multiple clock domains. Verify that the target output formats (LVPECL, LVDS, HCSL, etc.) align with the receiver specifications. Confirm that the input reference source matches the supported frequency ranges and signal types defined in the datasheet.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'B' suffix typically denotes a specific factory-programmed configuration variant within the series. The '-GMR' suffix indicates the tape-and-reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements within the same package and pinout include other Si5338 variants such as SI5338A-B or SI5338Q-B. When substituting, verify that the new part supports the required output frequencies and formats, as different suffixes may have distinct factory-programmed settings.
