Hi all,
I have question regarding a buffer.
I have 80MHz oscillator (50% duty cycle square wave) which was driving my DUT but the trace capacitance was high (100p) so the oscillator was loaded big time and therefore I was getting a really bad output.
Then I added buffer 74HC/HCT125 (14 pin DIP package) to the output of the oscillator now I get a clean output from the oscillator but the buffer output which still sees a high trace capacitive load looks like a sine wave.
Any suggestions
