621SDCGI Overview
There is a case option of 8-SOIC (0.154, 3.90mm Width) available for this clock divider. There is a Tube packaged with it. Normal operation is limited to 200MHz. As far as I can tell, it is mounted by Surface Mount. Electronic parts classified as Buffer are considered to be safety components. It is recommended to set the temperature to -40°C~105°C so the system can perform reliably. In order for it to function, a power source of 1.71V~3.465V V must be available. As a result, the output is LVCMOS.
