I use for the communication between 2 boards this component:
FIN212ACMLX
Like serializer:
I connect to clkref and strobe a clock of 12 MHz
I connect to "1" S0-S1
I connect to "1" PLL0 "0" PLL1 and DIRI to "1"
IMHO must work also if not connected the other board, instead i don't see nothing on pin 21-22-23-24.
I check with oscilloscope ..i don't see waveform on pin 21-22-23-24.
Does anyone know this component?
What is a FIN212ACMLX?
Post a link to the datasheet.

These pins are differential outputs, you don't have necessarily to see any voltage change against GND.
With a 12bit input signal at 40MHz this device seems to be out of reach for an arduino. Please describe what relationship you see in your question to Arduino. Remember this is an Arduino forum (maybe with the exception of the General Electronics topic).
Thank you Pylon:
Yes maybe this topic it was better in General Electronics.
IMHO i must always see something also if the pins are differenzial output.
For me it's impossibile see nothing...where is the infomation and how can i check if the componet works?

No, you don't have to see something, although you probably would with most chips, given you connected just one channel! What do you see on the outputs? Just white noise?
If you want to see the actual output waveform, connect the GND of your scope's input to the negative signal pin and the main input to the positive. Take care to connect only of the two signals to the scope otherwise you produce a short circuit.
Thank you for you help
Now see some waveform.
I use 4 device (2 fo board) for the comunication between 2 boards
So in the first board (master) i have a CLKREF of 12Mhz.
The second board i haven't CLKREF and i connect (to serilializer) the CKP of deserializer to serializer.
OK?
