SI5338N-B06122-GMR

Overview

The SI5338N-B06122-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential signals.

Feature Summary

• Four independent output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options: external crystal (8–30 MHz), CMOS (5–200 MHz), and differential (5–710 MHz)
• Independent output voltage selection per driver: 1.5 V, 1.8 V, 2.5 V, or 3.3 V

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout configuration and factory programming settings. Ensure compatibility with the required I²C bus voltage levels and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when zero ppm frequency accuracy is required across multiple outputs. Confirm that the desired output signal formats and supply voltages align with the device's configurable driver capabilities. Validate that the input reference frequency range matches the available source, whether it be a crystal oscillator or a high-frequency differential clock.

Part Context
