Twisted Pair Interface LED
Output I O
TWISTED PAIR TRANSMIT OUTPUTS These high drive CMOS level outputs are
resistively combined external to the chip to produce a differential output signal with
equalization to compensate for Intersymbol Interference (ISI) on the twisted pair medium
TWISTED PAIR RECEIVE INPUTS These inputs feed a differential amplifier which passes
valid data to the ENDEC module
AUI TRANSMIT OUTPUT Differential driver which sends the encoded data to the
transceiver
AUI RECEIVE INPUT Differential receive input pair from the transceiver
AUI COLLISION INPUT Differential collision pair input from the transceiver
ACTIVITY An open-drain active low output It is asserted for approximately 50 ms
whenever the DP83907 transmits or receives data in either AUI or TPI modes
COLLISION An open-drain active low output It is asserted for approximately 50 ms
whenever the DP83907 detects a collision in either either AUI or TPI modes
GOOD LINK An open-drain active low output This pin operates as an output to display link
integrity status if this function has not been disabled by the GDLNK bit in Configuratioin
Register B
This output is off if the DP83907 is in AUI mode or if link testing is enabled and the link
integrity is bad (i e the twisted pair link has been broken)
This output is on if the DP83907 is in Twisted Pair interface (TPI) mode link integrity
checking is enabled and the link integrity is good (i e the twisted pair link has not been
broken) or if the link testing is disabled
EQUALIZATION RESISTOR A resistor can be connected from this pin to GND or V
change the equalization of the TP output
TRANSMIT LEVEL RESISTOR A resistor can be connected from this pin to GND or V
change the TP output amplitude level
CRYSTAL ON EXTERNAL OSCILLATOR INPUT
CRYSTAL FEEDBACK OUTPUT Used in crystal connections only Should be left
unconnected when using an oscillator module
THIN CABLE This output is high if DP83907 is configured for thin cable It can be used to
enable the DC-DC converter required by the thin Ethernet configuration
