STL60444 Datasheet The TX100 Driver outputs the differential signal onto the TXOP and TXON pins. It operates with l:root 2 magnetics to provide impedance matching and amplification of the signal in accordance with the 802.3 specifications. The transmit current is governed by the current through the TXREF100 pin, which must be grounded through a resistor as described in "External Components". The TX100 driveris disabled in 10BASE-T mode and in loop back mode.lf no data is being transmitted from the MAC, the NWK933 outputs idle symbols of 11111 (suitably scrambled).
