SI5338N-B06178-GM

Overview

The SI5338N-B06178-GM is a programmable 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 formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. 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. Inputs accept external crystals (8–30 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz), or differential signals (up to 710 MHz). Outputs reach up to 710 MHz for differential and 350 MHz for single-ended configurations.

Procurement Notes

Verify the specific ordering suffix B06178 against the manufacturer's official documentation to confirm the programmed configuration. Ensure the I2C pull-up voltage meets the required standard by writing register 27 if the bus voltage is below 2.5 V. Confirm package type is 24-QFN (4x4 mm) and check temperature range specifications (-40 to +85 °C) for the target application environment.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single programmable source. Ensure the required output frequencies fall within the supported ranges: up to 710 MHz for differential outputs and up to 350 MHz for single-ended outputs. Verify that the input reference signal matches one of the supported types, such as an external crystal between 8 and 30 MHz or a differential input up to 710 MHz.
