CML Output Buffer

The CML outputs of the MAX3747A/MAX3747B limiting

amplifiers provide high tolerance to impedance mis-

matches and inductive connectors. The output current

is approximately 16mA for the MAX3747A/MAX3747B.

Connecting the DISABLE pin to V

disables the out-

put. If the LOS pin is connected to the DISABLE pin,

the outputs OUT+ and OUT- are at a static voltage

(squelch) whenever the input signal level drops below

the LOS threshold. The output buffer can be AC- or DC-

coupled to the load (Figure 4).
