A 36-WFQFN Exposed Pad case is used for packaging. It is packaged as a Tube. It is recommended that the maximum value for normal operation is 1.4GHz. A total of 36 terminations have been found in it. Using a supply voltage of 3.3V allows for high efficiency. As far as I can tell, it is mounted by Surface Mount. An electronic component classified as Fanout Buffer (Distribution), Divider is categorized as such. If you wish to ensure reliable performance, you should set the temperature to -40°C~105°C. The clock switch should operate with a voltage of 3.15V~3.45VV. There are 36 pins on the clock buffer. The output is LVCMOS, LVDS. Basically, it belongs to the same family as the LTC6954. Vsup is set to 3.45V as the maximum supply voltage.
