SI53327-B-GMR Overview
There is a case option of 24-VFQFN Exposed Pad available for this clock divider. There is a Tape & Reel (TR) packaged with it. Normal operation is limited to 1.25GHz. As far as I can tell, it is mounted by Surface Mount. Electronic parts classified as Fanout Buffer (Distribution), Multiplexer are considered to be safety components. It is recommended to set the temperature to -40°C~85°C so the system can perform reliably. In order for it to function, a power source of 2.38V~3.63V V must be available. As a result, the output is LVPECL.
