Datasheet
Datasheet Summary
Powered by GS/AI

The 1266963-SI5344H-D-GM is a high-frequency clock generator and jitter attenuator designed for applications requiring precise timing. It supports output frequencies up to 2.75 GHz in High-Frequency Mode and 717.5 MHz in MultiSynth Mode, with low phase jitter performance of less than 50 fs typical for high frequencies and less than 150 fs for MultiSynth outputs. The device operates over an input frequency range of 8 kHz to 750 MHz and features programmable jitter attenuation bandwidth from 10 Hz to 4 kHz. This clock generator is highly configurable, supporting various output formats including LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable voltage swing and common mode settings. It includes features such as status monitoring, hitless input clock switching, and automatic free-run and holdover modes. The device is programmable via a serial interface (I²C or SPI) and includes in-circuit programmable non-volatile memory for frequency configuration retention. The Si5344H operates within a temperature range of -40°C to +85°C and is housed in a 44-QFN package. It is suitable for high data rate coherent optical transceiver designs and other applications requiring precise clock generation and jitter attenuation.
