Skyworks Solutions, Inc. Clock Generators, PLLs, Frequency Synthesizers SI5345B-B05655-GMR

The SI5345B-B05655-GMR is a highly versatile clock generator and jitter attenuator that utilizes fourth-generation 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 application requirements. It includes multiple operational modes such as free-run, synchronous, and holdover, along with hitless input clock switching capabilities. The device is designed for compatibility with various output formats, including LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable signal amplitude. The SI5345B is packaged in a 64-QFN 9vó9 mm form factor and operates within a temperature range of -40 to +85 °C. It is programmable via a serial interface (I²C 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.
