SI5355A-B05455-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5355A-B05455-GMR is a programmable clock generator from the Si5355 series, manufactured by Skyworks Solutions. It features eight CMOS outputs organized into four independent banks, each capable of synthesizing frequencies up to 200 MHz with 0 ppm error using MultiSynth technology. The device supports input references of 25 or 27 MHz crystals or 5–200 MHz CMOS clocks. It operates on core supply voltages of 1.8 V, 2.5 V, or 3.3 V and output supplies of 1.71 V to 3.63 V. Key electrical parameters include a typical core current of 45 mA, period jitter of 50 ps pk-pk, and phase jitter of 2 ps rms (12 kHz–20 MHz). It is housed in a 24-QFN package and functions within an industrial temperature range of –40 °C to +85 °C.
