SI5338N-B06144-GMR

Overview

The SI5338N-B06144-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision and typical phase jitter of 0.7 ps RMS. The device supports differential outputs up to 710 MHz and single-ended formats up to 350 MHz. It operates from a 1.8, 2.5, or 3.3 V core supply with a typical current of 45 mA. Configuration is performed via an I2C/SMBus interface, and the unit is housed in a compact 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent, glitchless frequency synthesis on four outputs
• Supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL output formats
• Typical phase jitter of 0.7 ps RMS for high-performance timing applications
• I2C/SMBus compatible programming interface

Applications

• PCIe Gen 1/2/3/4 common clock generation
• Ethernet switch and router timing
• FPGA and processor clocking
• Telecom line cards and broadcast video/audio timing

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B06144 suffix against the target design requirements. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern specifications provided in the datasheet.

Selection Notes

Select this component when independent frequency synthesis across multiple domains is required. Ensure the input reference source matches the supported formats, such as differential inputs up to 710 MHz or external crystals between 8 and 30 MHz. Validate that the output voltage levels (1.5V to 3.3V) are compatible with the receiving devices.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' designation typically indicates a specific factory-programmed variant within the series, distinct from generic unprogrammed versions. The '-GMR' suffix denotes the tape-and-reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements include other Skyworks Si5338 variants such as SI5338N-B-GMR or SI5338A-B-GMR. Verify that the substitute part number supports the same output configurations and frequency ranges required by the application.
