Part Number: LMK1C1102
If a 100MHz sin wave is feeding into the input of LMK1C1102 with 0.9v(0~1.8v) amplitude. Is the output 50% duty cycle?
If not, can I buy other component with 50% duty cycle. thanks a lot!
Datasheet guarantees 45%-55% output duty cycle for 50% duty cycle input. For your 100MHz input, you would want to supply VDD = 1.8V so that the input swings around the input threshold of VDD/2 for 50% duty. If you used 3.3V or 2.5V for example, there would be duty cycle distortion when DC-coupled.

In reply to Lane Boyd:
Thanks Lane. If the output is about 50% duty cycle with 100MHz sin wave. Is output a sin wave or square wave?
I need a clock buffer for digital IC. It's requirement is it should be square.
If the output is sin wave, the digital IC may not work well. Thanks in advance.
In reply to mike meng:
The output is a square wave
