Figure 2 is an external component diagram showing
how to implement the transmit mode collision detect
levels recommended by IEEE 802.3. Figure 3 on the
following page shows how to implement the receive
mode collision detect levels recommended by
IEEE 802.3. Receive mode collision detect threshold
levels of the Am7996 are implemented by adding R9,
R10 and C4. For the values of the components shown in
Figure 3, a nominal receive mode collision detect
threshold of –1.5 V, for a –1.404 V to –1.581 V window,
is achieved.
