SI5338L-B05675-GMR

Overview

The SI5338L-B05675-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 generation with zero ppm precision and features low phase jitter of 0.7 ps RMS typical. The device accepts various input references including differential clocks up to 710 MHz and single-ended inputs up to 200 MHz. Outputs are configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V per driver. It operates from a single core supply of 1.8, 2.5, or 3.3 V within a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Low phase jitter performance of 0.7 ps RMS typical across all outputs.
• Flexible input reference options: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz).
• Independently configurable outputs support multiple signal formats including LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), and CMOS (up to 200 MHz).

Applications

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

Procurement Notes

Verify the specific ordering suffix B05675 against the manufacturer's current documentation to confirm factory-programmed parameters. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure I2C pull-up voltage compatibility with the system bus if operating below 2.5 V.

Selection Notes

Select this component when designing systems requiring four independent clock signals with precise frequency accuracy and low jitter. Ensure the required output voltage levels (1.5, 1.8, 2.5, or 3.3 V) match the load requirements. Verify that the input reference source falls within the supported frequency ranges for the chosen input pin configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It is designed to replace multiple discrete oscillators in high-performance digital systems. The device integrates a PLL and MultiSynth synthesizers to generate clean clock signals from a single reference source.

Replacement Considerations

Direct replacement requires matching the QFN-24 package and pinout. Verify that the new component supports the same output formats and frequencies. Check if the target application requires specific factory-programmed frequencies that must be replicated.
