SI5338N-B06142-GM

Overview

The SI5338N-B06142-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 performed via an I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference supporting external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Processor and FPGA clocking
• Telecom line cards
• Fibre Channel, SAN

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 compatibility matches the system bus requirements, particularly if operating below 2.5 V.

Selection Notes

Select this component for designs requiring multiple independent clock frequencies from a single package. Verify that the required output signal formats (LVPECL, LVDS, etc.) and frequencies are supported by the specific output driver configurations available in the selected variant.
