Loopbacki When High, forces internal loopback. Disables collision and the transmission of both data and link pulses. Pulled Low internally. Transmit Enablei Enables data transmission and starts the watchdog timer. Synchronous to TCLK. Pulled Low internally. Transmit Clocki A 10 MHz clock output. This clock signal should be directly connected to the transmit clock input of the controller. Transmit Datai Input signal containing NRZ data to be transmitted on the network. TXD should be connected directly to the transmit data output of the controller. Pulled Low internally. Collision Signali Output that drives the collision detect input of the controller.

Output is pulled Low during link test pass. Pulled High internally. Carrier Detecti An output for notifying the controller that activity exists on the network. Receive Clocki A recovered 10 MHz clock which is synchronous to the received data and connected to the controller receive clock input. Receive Datai Output signal connected directly to the receive data input of the controller. Link Enablei Controls link integrity test; enabled when LI is High, disabled when LI is Low. Bias Circuitryi A 7.5 k 1% resistor to ground at this pin controls operating circuit bias. SQE Disablei When DSQE is High, the SQE function is disabled. When DSQE is Low, the SQE function is enabled. SQE should be disabled for normal operation in Hub/Switch/Repeater applications. Pulled Low internally. Twisted Pair Outputsi Differential outputs to the twisted-pair cable. The outputs are pre-equalized. Mode Select 0 DQG ii Mode select pins determine controller compatibility mode in accordance with Table 2. Pulled Low internally. Twisted-Pair ,QSXWVi A differential input pair from the twisted-pair cable. Receive filter is integrated on-chip. No external filters are required.
