SI5338L-B05700-GMR

Overview

The SI5338L-B05700-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports any frequency up to 710 MHz with 0 ppm precision and features low phase jitter of 0.7 ps RMS typical. The device accepts various input references including external crystals (8–30 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz), and differential inputs (up to 710 MHz). Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply of 1.8, 2.5, or 3.3 V, draws 45 mA typical current, and functions within a temperature range of –40 to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.

• PCIe Gen1/2/3/4 timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific factory-programmed configuration associated with the B05700 suffix against the target design requirements. Confirm that the GMR suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure I2C/SMBus interface compatibility with the host controller's voltage levels and bus speed before integration.

Selection Notes

Select this component when independent, glitch-free frequency adjustments and precise phase alignment across multiple outputs are required. Consider the Si5338L variant if the application demands high-frequency differential outputs up to 710 MHz. Verify that the available input reference frequencies fall within the supported ranges for the desired output formats and voltage levels.

Part Context

The SI5338L-B05700-GMR belongs to the Si5338 family of I2C-programmable clock generators. This series replaces multiple discrete oscillators by synthesizing any frequency on each of its four output drivers. The 'L' designation typically denotes specific performance or feature sets within the family, while the alphanumeric suffix defines the factory-programmed NVM content for the specific frequency plan.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants such as SI5338B, SI5338Q, or SI5338N, provided their factory-programmed configurations match the system requirements. Verify that the replacement part supports the necessary output frequencies and signal formats.
