Silicon Labs Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5342D-B04021-GM

The SI5342D-B04021-GM is a clock generator and jitter attenuator that supports a wide range of applications, including networking line cards and synchronous Ethernet. It features four input clocks and two output clocks, with an output frequency range of 100 Hz to 1028 MHz for differential outputs and up to 250 MHz for LVCMOS outputs. The device is designed to provide ultra-low jitter performance of 90 fs rms and is capable of generating any combination of output frequencies from any input frequency. The SI5342D supports programmable jitter attenuation bandwidth from 0.1 Hz to 4 kHz and offers compatibility with various output formats, including LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable signal amplitude. It includes features such as hitless input clock switching, free-run and holdover modes, and status monitoring capabilities. The device operates within a temperature range of -40 to +85 ¬8C and is packaged in a compact 44-QFN 7vó7 mm form factor. The configuration can be easily managed through a serial interface using I¬=C or SPI, and it is programmable via non-volatile memory.
