ML4658 SYSTEM DESCRIPTION (Continued) The transmitter incorporates a pre-equalization circuit for driving the twisted pair line. Pre-equalization compensates for the amplitude and phase distortion introduced by the twisted pair cable. The twisted pair line will attenuate the 10MHz signal more ...
Page 13
SYSTEM DESCRIPTION (Continued) When data is received by the chip while transmitting, a collision condition exits. This will cause the collision oscillator to turn on within 9 bit times. The data on the DI AUI pair (Rx+, Rx–) changes from ...
