ADG3304 problem 3.3V to 1.8V

Hello everyone,


We are trying to program a CPU which is on 1.8 with a device that is on 3.3 so we needed to translate the voltages. We are using ADG3304 for that purpose.
We connected everything correctly and the clock signal doesn't work properly. We connected both voltages to VCCA and VCCY  and we tried putting EN on 1.8 and 3.3. The problem is that the clock which is 2.5 MHz (we tried 100 kHz too) goes into the chip but on the other side comes out some gibberish that has the same frequency but is deformed and oscillates between the voltages of 1.0 and 1.3.


Has anybody encountered the same problem? I can supply a schematic but it has some unneeded details.
