It's a electronic part of the 12-TSSOP (0.118, 3.00mm Width) package. Tube is the form in which it is packaged. There is a maximum value of 300MHz for normal operation. In it, there are 12 terminations. With a voltage of 3.3V, high efficiency is possible. As a result, it will be mounted by Surface Mount in this case. Electronic components classified as Fanout Buffer (Distribution) fall into this category. The temperature should be set to -40°C~125°C to ensure reliable performance. In general, it should be able to work with a power source of 3.15V~3.45V volts. It's in the way of Surface Mount. There are 12 pins on the clock buffer. There is LVPECL output from clock driver. A 12 pin is used for operation. This object belongs to the LTC6957 family. There is a default setting of output 2. Keeping the supply voltage at 3.3V is the key to maximizing the efficiency of the system.
