Twisted-Pair Output, Positive and Negative. Differential driver pair produces 802.3-
compliant pulses for either 100BASE-TX or 10BASE-T transmission.
Transmit Reference. Tie to center tap of output transformer.
Twisted-Pair Input, Positive and Negative. Differential input pair for either 100BASE-TX
or 10BASE-T reception.
Speed LED. Active Low output indicates 100 Mbps operation is selected.
Receive LED. Active Low output indicates that receiver is active.
Transmit LED. Active Low output indicates transmitter is active.
Link LED. Active Low output;
During 100 Mbps operation, indicates scrambler lock and receipt of valid Idle codes.
During 10 Mbps operation, indicates Link Valid status.
Collision LED. In default mode, active Low output indicates collision. However, LEDC is
programmable and may be set for other indications. For programming options, see
Configuration Register 19 in
page
Test. Must be tied Low.
Crystal Input and Output. Use a clock at XI or connect a 25 MHz crystal oscillator across
XI and XO. Refer to the Functional Description section for detailed clock requirements on
page
Bias Control. Controls operating circuit bias via an external 22.1 kΩ, 1% resistor to
ground.
Reset. This active Low input is OR’ed with the control register Reset bit (0.15). The
LXT970A Transceiver reset cycle is extended 300 μs (nominal) after Reset is de-asserted.
Power Down. When High, forces LXT970A Transceiver into power down mode. This pin is
OR’ed with the Power Down bit (0.11). Refer to
No Connection. Leave open.
