Clock Generators, PLLs, Frequency Synthesizers datasheet and documents for SI5345A-B04957-GMR

SI5345A-B04957-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345A-B04957-GMR is a factory preprogrammed clock multiplier and jitter attenuator from the Si5345 family. It features four inputs and ten outputs, supporting integer and fractional synthesis with output frequencies up to 1028 MHz. The device utilizes fourth-generation DSPLL technology for ultra-low jitter performance of 90 fs rms. It operates on a single 1.8 V core supply and accepts differential or LVCMOS input signals ranging from 8 kHz to 750 MHz. The component is housed in a 64-QFN package and supports I2C/SPI serial interfaces.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Generates any combination of output frequencies from any input frequency using integer and fractional synthesis modes.
Provides ultra-low jitter attenuation of 90 fs rms via fourth-generation DSPLL technology.
Supports hitless input clock switching between fractionally related sources.
Includes in-circuit programmable non-volatile memory for known power-up configuration.
