Silicon Labs Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5345A-B04208-GMR

The SI5345A-B04208-GMR is a highly versatile clock generator and jitter attenuator that utilizes advanced DSPLL,Ñ¢ and MultiSynth,Ñ¢ technologies. It is capable of generating any combination of output frequencies from a wide range of input frequencies, with an ultra-low jitter performance of 90 fs rms. The device supports input frequencies from 8 kHz to 750 MHz for differential signals and up to 250 MHz for LVCMOS signals. Its output frequency range extends from 100 Hz to 1028 MHz for differential outputs and up to 250 MHz for LVCMOS outputs. This clock generator features programmable jitter attenuation bandwidth, allowing for optimization based on specific application requirements. It is compliant with ITU-T G.8262 (SyncE) standards and offers highly configurable outputs compatible with various signaling standards, including LVDS, LVPECL, LVCMOS, CML, and HCSL. The device includes features such as hitless input clock switching, free-run and holdover modes, and status monitoring capabilities. The SI5345A-B04208-GMR operates within a temperature range of -40 to +85 ¬8C and is packaged in a compact 64-QFN 9x9 mm form factor. It is programmable via a serial interface (I¬=C or SPI) and includes in-circuit programmable non-volatile memory for configuration retention. This product is suitable for applications in OTN muxponders, networking line cards, synchronous Ethernet, and broadcast video systems.
