SI5344H-C05857-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5344H-C05857-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 less than 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). Operating conditions include a core voltage of 1.8 V ±5% and an analog supply of 3.3 V ±5%, with a temperature range from -40°C to +85°C.
