Abstract: The MAX3265 has CML outputs and the MAX3875 has CML inputs, which makes interfacing the two relatively straightforward. The main consideration in accomplishing this interface is to be aware that the pull-up resistors in the MAX3265 CML output structure are 100 ohm rather than 50 ohm. This is done to facilitate operation in >50 ohm environments.
