There is a case of 20-TSSOP (0.173, 4.40mm Width) in which it is packaged. In case Tape & Reel (TR), the cut smart buffer is available. For normal operation, 700MHz is the maximum value. As far as I can tell, it is mounted by Surface Mount. Electrical components classified as Fanout Buffer (Distribution), Multiplexer are classified as such. When the temperature is set to -40°C~85°C, reliable performance is ensured. It should be able to work with a power source of 3.135V~3.465VV. There is HSTL output from clock driver. Basically, it belongs to the same family as the ICS85214.
