Other Parts Discussed in Thread: THS3092, TINA-TI
Hello All,
I am trying to use THS4222 as a buffer for 40MHz and 48MHz signals. below is the circuit in TINA
When taking a transient response i could see a phase difference between the input and output signals. In addition to this if the i/p voltage is 0 to 1.8V the o/p seen is -0.01V to 1.81V (i.e 10mV stretch in the input signals). I went through the datasheet and i couldn't find anything related to this. Can't this opamp be used for G=1 for 40M and 48M signals. Please clarify the below
1. Why there is a phase shift with the input and output 2. Why there is a 1mV stretch in the signals.
Attached the transient response below
Thanks in advance
