Name and Function
Positive side of the differential output driver pair that drives 10 Mb s
Manchester Encoded data on the TRMT pair of the AUI cable (Data Out A)
Negative side of the differential output driver pair that drives 10 Mb s
Manchester Encoded data on the TRMT pair of the AUI cable (Data Out B)
The positive input to a differential amplifier connected to the RCV pair of the
AUI cable (Data In A) It is driven with 10 Mb s Manchester Encoded data
The negative input to a differential amplifier connected to the RCV pair of the
AUI cable (Data In B) It is driven with 10 Mb s Manchester Encoded data
The positive input to a differential amplifier connected to the CLSN pair of the
AUI cable (Collision In A)
The negative input to a differential amplifier connected to the CLSN pair of the
AUI cable (Collision In B)
TRANSMIT DATA HIGH Active high Manchester Encoded data to be
transmitted onto the twisted pair This signal is used in conjunction with TDL
TDH and TDL to generate the pre-conditioned twisted pair output waveform
TRANSMIT DATA LOW Twisted Pair Output Driver Active high Manchester
Encoded data with embedded pre-distortion information to be transmitted onto
the twisted pair This signal is used in conjunction with TDH TDH and TDL to
generate the pre-conditioned twisted pair output waveform
TRANSMIT DATA HIGH INVERT Twisted Pair Output Driver Active low
Manchester Encoded data to be transmitted onto the twisted pair This signal
is used in conjunction with TDL TDH and TDL to generate the pre-
conditioned twisted pair output waveform
TRANSMIT DATA LOW INVERT Twisted Pair Output Driver Active low
Manchester Encoded data with embedded pre-distortion information to be
transmitted onto the twisted pair This signal is used in conjunction with TDL
TDH and TDH to generate the pre-conditioned twisted pair output waveform
Active high Manchester Encoded data received from the twisted pair
Active low Manchester Encoded data received from the twisted pair
20 MHz CRYSTAL INPUT This pin can be driven with an external MOS level
clock when X2 is left floating This input provides the timing for all of the
82595TX functional blocks
20 MHz CRYSTAL OUTPUT If X1 is driven with an external MOS level clock
X2 should be left floating
