Original question:

CDCE62002: Is it possible to use LVCMOS25 (with ac coupled capacitor) to drive AUX_IN input?

Hi are using CDCE62002 for recovered clock jitter cleaner. As in development board we are giving LVCMOS input 31.4 MHZ but we dont see any output. Can you let us know how to resolve the issue.

The dev kit says:

T.The second input(AUXIN)can support a crystal in the frequency range of 2MHz to 42MHz or a single ended input (LVCMOS) upto70MHz.The CDCE62002 EVM provides support for driving the AUXIN signal from a non-board5mmx3.2mmSMDcrystal. If the AUXIN is alternately driven by the SMA,the on-board crystal has to be removed and R65 should be populated with a 0Ω resistor.
