SI5344A-B04582-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344A-B04582-GM is a factory preprogrammed clock synthesizer and jitter attenuator from the Si5344 family. It features four inputs and four outputs, supporting integer and fractional frequency synthesis with output frequencies up to 1028 MHz. The device utilizes fourth-generation DSPLL technology to achieve ultra-low jitter performance of 90 fs rms. It operates within a temperature range of -40°C to +85°C and is housed in a 44-QFN package measuring 7x7 mm.
