Silicon Labs Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5345A-B05745-GM

The SI5345A-B05745-GM is a highly versatile clock generator and jitter attenuator designed for applications requiring precise clock generation and low jitter performance. It features a programmable architecture that allows for the generation of any combination of output frequencies from a wide range of input frequencies, with an ultra-low jitter specification 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. Output frequencies can range from 100 Hz to 1028 MHz for differential outputs and up to 250 MHz for LVCMOS outputs. The device is compliant with ITU-T G.8262 (SyncE) standards and offers highly configurable output options compatible with various signaling standards including LVDS, LVPECL, LVCMOS, CML, and HCSL. It includes features such as programmable jitter attenuation bandwidth, hitless input clock switching, and free-run and holdover modes. The SI5345A-B05745-GM operates within a temperature range of -40 to +85 ¬8C and is packaged in a 64-QFN 9x9 mm form factor. It is programmable via I2C or SPI interfaces and supports in-circuit programming with non-volatile memory, making it suitable for a variety of networking and synchronization applications.
