LTC 6955 some problem

Hi CrusadeLee,

If you are asking about AD9266, it can take a single ended clock. Figure 50 in the RevB AD9266 datasheet shows an example circuit.

At 125℃ you must use the AD9266-EP version.

Thanks,

Thanks,I want to know ltc6955 how to use Single-ended square  wave Clock as the input Clock  Or don't allowed? Because the ltc6955 only show sine wave as the input clock or differential Clock in chip document, I worry if I make the pcb.,the ltc6955 can't work well.

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.

Yes, the LTC6955 works fine with sine or square with either SE or differential.   The LTC6953 and LTC6955 have the exact same design for the input pins.  For some reason we forgot to include this schematic in the LTC6955 datasheet.  You can use this one.  

Thank your help to resolve my problem!

Best Regardless
