SI5338N-B06144-GM

Overview

The SI5338N-B06144-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It 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 managed via an I2C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Independent output voltage per driver selectable at 1.5, 1.8, 2.5, or 3.3 V.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps resolution.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE interfaces.
• Processor and FPGA clocking solutions.
• Broadcast video/audio timing distribution.
• Telecom line cards and MSAN/DSLAM/PON equipment.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout configuration and factory programming settings. Ensure the I2C pull-up voltage matches the system bus requirements, as register adjustments may be necessary for voltages below 2.5 V. Confirm thermal management meets the junction temperature limits specified in the datasheet.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the desired output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the supported ranges. Check if the application requires spread spectrum modulation or specific jitter performance metrics such as PCIe compliance.
