SI5342H-C-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5342H-C-GM is a jitter attenuator and clock multiplier featuring four inputs and two outputs housed in a 44-QFN package. It supports differential input frequencies from 8 kHz to 750 MHz and LVCMOS inputs up to 250 MHz. The device generates output frequencies ranging from 100 Hz to 1028 MHz using integer-only synthesis modes. Core supply voltage (VDD) operates at 1.8 V ±5%, while analog supplies (VDDA) support 3.3 V, 2.5 V, or 1.8 V configurations. Operating temperature ranges from -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact frequency synthesis mode and package variant. Ensure that the selected part number matches the required integer-only capability if applicable. Cross-reference the datasheet revision date to confirm compatibility with current design specifications before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when an integer-only frequency synthesis architecture is required for deterministic clock distribution. Verify that the maximum output frequency of 1028 MHz meets system requirements. Confirm that the 44-QFN package dimensions align with the PCB land pattern. Evaluate whether the dual-output configuration suffices for the target application topology.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5345/44/42 Rev D family of jitter attenuators. It shares core architectural features with the Si5344 and Si5345 models but offers a reduced pin count and fewer output channels. The family utilizes proprietary MultiSynth technology to achieve ultra-low jitter performance across various networking and telecommunications applications.
