APPLICATIO S I FOR ATIO
Note that due to the 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.
