9.14.5 Collision Detection Function
9.14.6 Link Integrity
Revision 1.0 (10-24-08)
In the 10BASE-T mode, a collision state is indicated when there are simultaneous transmissions and
receptions on the twisted pair link. During a collision state, the nCOLL signal is asserted. If the received
data ends and the transmit control signal is still active, the transmit data is sent to the MAC within 9 bit
times. The nCOLL signal is de-asserted within 9 bit times after the collision terminates. In the AUI mode,
the external transceiver sends a 10MHz signal to the PHY upon detection of a collision.
The PHY test for a faulty twisted-pair link. In the absence of transmit data, link test pulses are transmitted
every 16+/-8ms after the end of the last transmission or link pulse on the twisted pair medium. If neither
valid data nor link test pulses are received within 10 to 150ms, the link is declared bad and both data
transmission as well as the operational loopback function are disabled. The Link Integrity function can be
disabled for pre-10BASE-T twisted-pair networks.
