The CML outputs of the MAX3747/MAX3747A/
MAX3747B limiting amplifiers provide high tolerance to
impedance mismatches and inductive connectors. The
output current is approximately 10mA for the MAX3747
and 16mA for the MAX3747A/MAX3747B. Connecting
the DISABLE pin to V
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).
The MAX3747 output is 500mV
MAX3747B output is 800mV
