Silicon Labs Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5344B-B03750-GM

The SI5344B-B03750-GM is a clock generator that features four input clocks and four output clocks, housed in a 44-QFN package measuring 7x7 mm. It is capable of generating output frequencies ranging from 100 Hz to 1028 MHz for differential signals and up to 250 MHz for LVCMOS signals. The device supports a wide input frequency range of 8 kHz to 750 MHz for differential inputs and 8 kHz to 250 MHz for LVCMOS inputs. This clock generator utilizes advanced DSPLL and MultiSynth technologies for jitter attenuation, achieving ultra-low jitter performance of 90 fs rms. It offers programmable jitter attenuation bandwidth from 0.1 Hz to 4 kHz, and features such as hitless input clock switching, free-run and holdover modes, and programmable signal amplitudes compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL outputs. The device operates within a temperature range of -40 to +85 °C and is compliant with RoHS standards. The SI5344B-B03750-GM is suitable for applications in networking line cards, synchronous Ethernet, and broadcast video, making it a versatile choice for engineers requiring high-performance clock generation and jitter management.
