AMS 2632 Crosstalk Isolation

AMS 2632 has a requirement for transmit and receive crosstalk separation to be at least 40db. I'm exposing my lack of smarts when I ask this: "What are they talking about?"

More importantly, how do I measure it?

David,

I don't have access to that specific specification now, but cross talk is usually pertaining to the leak of signal between the transmitting and receiving crystals mounted side by side in a single housing (SE probes for example).

If the cross talk level was not specified, the S/N ratio of the received signal would be adversely affected.

Regards.

Swamy
