Good day.
Our customer have a question about clocking the LMX2491. In the datasheet is says that to use a differential clock with the chip one should use a 100Ω differential termination, and then AC couple the chip's osc pins to the clock signals.
It is their understanding that if the oscin pins are not internally biased this will expose these pins to negative voltages. In their case the maximum negative voltage that will be seen by these pins is about -800mV. Is this acceptable?
Thanks!
