SI5344H-C05141-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5344H-C05141-GM 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 <150 fs-rms (12 kHz–20 MHz). Operating conditions include a core voltage of 1.8 V ±5% and an analog supply of 3.3 V ±5%, with an operating temperature range from –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 official Skyworks ordering guide or datasheet errata. Confirm that the required frequency plan matches the programmed NVM settings before procurement. Ensure compatibility with the intended serial interface protocol (I2C or SPI) and input/output voltage levels.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring ultra-low jitter performance at frequencies exceeding 1 GHz alongside flexible lower-frequency outputs. The Si5344H provides four outputs, whereas the Si5342H offers only two; choose based on channel count requirements. Utilize ClockBuilder Pro software to validate the specific jitter tolerance and bandwidth settings for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344H/42H Rev D family of high-frequency clock multipliers. It is distinct from the Si5344A and Si5344B models, which are limited to maximum output frequencies of 1.028 GHz and 350 MHz respectively. The Si5344H is specifically engineered for coherent optical networking applications demanding superior phase noise characteristics.
