I/O
DESCRIPTION
Input/Output, Non-Inverting Differential input, bidirectional control channel. The IO must be AC coupled
CML
with a 0.1-µF capacitor. Leave open if unused.
Input/Output,
CML
Inverting Differential input, bidirectional control channel. The IO must be AC coupled with a
0.1-µF capacitor. For applications using single-ended coaxial interconnect, a 0.047-µF AC
coupling capacitor should be placed in series with a 50Ω resistor before terminating to GND.
Leave open if unused.
