I have a chip with 1Vpp 50MHz sine-wave-clock output, but my another chip need a 3.3Vpp square-ware input. How can I easily realize this transition on the PCB? Or are there any clock drive/buffer chips for advice？Please tell me the chip's type or send me the datasheet if there are any suitable chips!
Thanks very much!
 

You need to use a high speed comparator with around 5nS prop delay, something like a TI TLV3501. Just connect like shown below. The RC on the - input finds DC average of the sine-wave and used to slice the sine-wave into a square-wave.
