LXT914 Flexible Quad Ethernet Repeater
10BASE-T Port Operation
10BASE-T Reception
Each LXT914 Repeater 10BASE-T port receiver acquires data packets from its twisted-pair input
(TPDIP/TPDIN). An internal RC filter and an intelligent squelch function discriminate noise from
link test pulses and valid data streams. The receive function is activated only by valid data streams
(above the squelch level and with proper timing). If the differential signal at the DI circuit inputs
falls below 75% of the threshold level (unsquelched) for eight bit times (typical), the port receiver
enters the idle state.
