Hi Eric
Why not just use a single resistor to terminate the differential mode,
which is the signal you are intrested in.
Tieing the center-tap to ground allows common mode currents to flow
which usually end up allowing power supply ground currents to get into
the sensitive signal paths.

Subject: [SI-LIST] : Combined single-ended/differential termination
package?
Hi,
We often use this termination scheme:
SIG+ -------+
|
R
|
+--C--+
| |
R V
| GND
SIG- -------+
That is, two resistors in series between the differential signals with a
center-tapped capacitor to ground. Is there a combined device to sucks
all these parts into a three-pin package?
Regards, Eric
