increased skew, this configuration might not operate at the
highest data rates. To transmit single-ended data over
short to medium distances, twisted pair is recommended
with the unused wire grounded at both ends (Figure 7).

Differential Transmission
Data rates up to 52Mbps can be transmitted over 100 feet
of high quality category 5 twisted pair. Figure 8 shows the
LTC1518 receiving differential data from an LTC1685
transceiver. As in the single-ended configurations, care
must be taken to properly terminate the differential data
lines to avoid unwanted reflections, etc.
