IDT49FCT3805EQI Overview
There is a case option of 20-SSOP (0.209, 5.30mm Width) available for this clock divider. There is a Tube packaged with it. Normal operation is limited to 166MHz. As far as I can tell, it is mounted by Surface Mount. Electronic parts classified as Fanout Buffer (Distribution) 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 3V~3.6V V must be available. As a result, the output is CMOS, LVTTL. This is a member of the family of IDT49FCT3805. It belongs to the 49FCT series of electronic parts.
