LTC 6955 some problem

I   use the LTC6955  as clock  distributer , im my circuit diagram, have seven ad9266s. the board work at  atmoshpere temperature is 125℃ at least four hours,(satisfy the target temperature only three types of chips). In the LTC6955 document, only supply single-ended sine wave signal  or Differential signal input, AD9266 work on 40MHZ  frequency(the ltc6955 clock source at 40Mhz), 

I'm sensitive the CLOCK JITTER and  work temperature and ADC sampling  Time synchronization,

    my question is : the input clock  can use single-ended square wave clock  as the input clock?,if can ,can give me a circuit diagram,

Best Regards

    Hi CrusadeLee,

    As you have seen, there are several examples in the LTC6955 datasheet showing a single ended clock input. It seems to me that a square wave would be fine, but we need to wait for confirmation from one of the engineers who knows the details of LTC6955.

    If we do not hear anything soon I'll directly ask one of them.
