Silicon Labs Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5344B-B05770-GM

The SI5344B-B05770-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 technologies such as DSPLL and MultiSynth, allowing for programmable jitter attenuation and the generation of any combination of output frequencies from any input frequency. It offers ultra-low jitter performance of 90 fs rms and features programmable jitter attenuation bandwidth from 0.1 Hz to 4 kHz. The device is compliant with ITU-T G.8262 (SyncE) standards and supports various output configurations, including LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable signal amplitude. The SI5344B also includes features such as hitless input clock switching, free-run and holdover modes, and status monitoring capabilities. It operates over a temperature range of -40 to +85 ¬8C and is RoHS compliant. The device can be configured easily using the ClockBuilder Pro software, which simplifies the programming process.
