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.
Kind regards,

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.
