Polarity Reverse Function
The LXT905 polarity reverse function uses both link pulses and end-of-frame data to determine the
polarity of the received signal.
If you disable Link Integrity testing, polarity detection is based only on received data. A
reversed polarity condition exists if the LXT905 detects eight consecutive opposite receive
link pulses, without receiving a link pulse of the expected polarity.
Reversed polarity also occurs if the LXT905 receives four consecutive frames with a reversed
start-of-idle.
Whenever the LXT905 receives a correct polarity frame or a correct link pulse, it resets these
two counters to zero.
If the LXT905 enters the link fail state, and does not receive any valid data or link pulses
within 96 to 128 ms, it resets the polarity to the default non-flipped condition.
Polarity correction is always enabled.
2.8
Collision Detection Function
A collision is the simultaneous presence of valid signals on both the TPI circuit and the TPO
circuit. The LXT905 reports collisions to the back-end via the COL pin. If the TPI circuit becomes
active while there is activity on the TPO circuit, the TPI data passes to the back-end over the RXD
circuit, disabling normal loopback. Figure 6 is a state diagram of the LXT905 collision detection
function.
