Datasheet
2.5.4.2
Data Errors
Figure 16
shows normal reception. When the LXT974/975 receives invalid symbols from the line,
it asserts RX_ER, as shown in
Figure 17
.
2.5.4.3
Collision Indication
Figure 18
shows normal transmission. The LXT974/975 detects a collision if transmit and receive
are active at the same time. As shown in
Figure 19
, upon detection of a collision, the COL output
is asserted and remains asserted for the duration of the collision.
