5.6.4
Carrier Sense
Carrier Sense (CRS) is an asynchronous output.
CRS is always generated when the LXT972M Transceiver receives a packet from the line.
CRS is also generated when the LXT972M Transceiver is in half-duplex mode when a packet
is transmitted.
Table 14
summarizes the conditions for assertion of carrier sense, data loopback, and collision
signals. Carrier sense is not generated when a packet is transmitted and in full-duplex mode.
5.6.5
Error Signals
When the LXT972M Transceiver is in 100 Mbps mode and receives an invalid symbol from the
network, it asserts RX_ER and drives “0101” on the RXD pins.
The TX_ER function that forces ‘H’ symbols out on the TPOP/TPON twisted pair is not
implemented in the LXT972M Transceiver.
5.6.6
Collision
The LXT972M Transceiver asserts its collision signal asynchronously to any clock whenever the
line state is half-duplex and the transmitter and receiver are active at the same time.
Table 14
summarizes the conditions for assertion of carrier sense, data loopback, and collision signals.
