... This resistor defines an internal reference current derived from an on-chip bandgap reference. Final output current at the 'TXO' outputs is a multiple of this current and is defined as:- Transition times of the 'TXO' outputs are matched and internally limited to approx. 2.5ns to reduce EMI emissions.

... NWK914D When N10/100 is held low the 10Mb/s driver is selected. This 10Mb/s driver consists of a differential analog buffer designed to take a fully cable conditioned 10Mb/s signal from the filter output of existing 10BASE-T electronics. The 10BASE-T signal is input on pins 10TXIN and 10TXIP. The output current of the buffer is determined by the same ...
