to compensate for the high frequency attenuation of the cable.

From the above measurements taken, the amount of jitter being added at each TX point is not significant. These tests were also run at line rates of
A standard connection to 100 and 120 unshielded twisted pair cabling is shown in Figure 16. Note that the transmit signal is somewhat attenu-
Also, the receive circuitry biases the positive and negative RX inputs to slightly different voltages. This is done so that the receiver does not receive
When connecting to UTP at 51.2Mbps and 204.8Mbps, it is necessary to use magnetics with sufficient bandwidth. Refer to Table 5 on page 20 for
