  Part Number: LMK1C1104 Hello. Can you please confirm that it is not a problem to use a 3.3V LVCMOS signal on the input clock when VCC=1.8V? There is no maximum specified in the datasheet for VIH, which leads me to believe that the "absolute" max of 3…

  Hi Jim, Can you give a little more information about this rise time issue. We can use CDCV304 which doesn't have 50ohm impedance. Its roughly around 25 ohm by looking at the I/V curves. Best, Asim
