SI5344H-C05141-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5344H-C05141-GMR is a high-frequency, ultra-low jitter attenuating clock multiplier with a digitally-controlled oscillator (DCO), manufactured by Skyworks Solutions. It features two inputs and four outputs in a QFN-44 package. The device supports High-Frequency Mode up to 2.75 GHz with typical phase jitter of 50 fs-rms (1 MHz–40 MHz) and MultiSynth Mode for any frequency up to 717.5 MHz with typical jitter under 150 fs-rms (12 kHz–20 MHz). Input frequencies range from 8 kHz to 750 MHz. Core supply voltage is 1.8 V ±5%, while output drivers support independent 1.8 V, 2.5 V, or 3.3 V supplies. Operating temperature spans –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the C05141 suffix against the required system specifications before procurement. Confirm that the GMR suffix indicates tape-and-reel packaging suitable for automated surface-mount assembly processes. Ensure compatibility with the intended serial interface protocol settings.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring precise clock generation for coherent optics or wireless infrastructure. Utilize ClockBuilder Pro software to configure the specific frequency plan and verify that the required output formats (LVDS, LVPECL, LVCMOS, CML, HCSL) align with the target receiver specifications. Consider the power dissipation limits when designing thermal management solutions.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344H family within the Si534x series of clock synthesizers. It shares the same QFN-44 package and core architecture as the Si5342H but provides four outputs instead of two. The device is designed to replace discrete jitter cleaner solutions by integrating all necessary filtering and control logic onto a single chip.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements within the same package include other Si5344H variants with different factory programming suffixes. Cross-family substitution requires careful evaluation of pinout compatibility and output driver capabilities.
