______________________________________________________________________________________
Termination
The MAX9217 has an integrated 100
Ω output-termina-
tion resistor. This resistor damps reflections from
induced noise and mismatches between the transmis-
sion line impedance and termination resistors at the
deserializer input. With PWRDWN = low or with the sup-
ply off, the output termination is switched out and the
LVDS output is high impedance.
Common-Mode Filter
The integrated 100
Ω output termination is made up of
two 50
Ω resistors in series. The junction of the resistors
is connected to the CMF pin for connecting an optional
common-mode filter capacitor. Connect the filter
capacitor to ground close to the MAX9217 as shown in
Figure 13. The capacitor shunts common-mode switch-
ing current to ground to reduce EMI.
