SI5338C-B05153-GMR

Overview

The Skyworks SI5338C-B05153-GMR 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 external crystals from 8 to 30 MHz. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats, supporting frequencies up 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, with typical jitter of 0.7 ps RMS.

Feature Summary

• Low phase jitter of 0.7 ps RMS typical
• Independent frequency increment/decrement for glitchless adjustments
• Highly configurable spread spectrum (SSC) capabilities
• I2C/SMBus compatible programming interface

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4 common clocking
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B05153 against the manufacturer's official documentation to confirm the exact pre-programmed configuration and pinout variant. Ensure compatibility with I2C bus voltage levels if operating below 2.5 V by checking register settings.

Selection Notes

Select this component when low jitter synthesis and flexible output formatting are required. Ensure the application supports the 4 x 4 mm QFN-24 package dimensions and thermal requirements. Verify that the required output frequencies fall within the supported ranges for the chosen signal format.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple crystal oscillators and functions as a frequency translator. The device integrates a PLL and MultiSynth dividers to generate precise clock signals from various reference sources.

Replacement Considerations

Direct replacements must match the Si5338 architecture and QFN-24 package. Verify functional equivalence regarding jitter performance, output drive strength, and I2C compatibility before substitution.
