Manufacturer:ALLEGRO Description:RECEIVE SIGNAL QUALIFICATION The integrated signal qualifier has separate squelch and un-squelch thresholds, and includes a built-in timer to ensure fast and accurate signal detection and receive noise rejection. Upon detection of two or more valid 10BASE-T or 100BASE-TX pulses on the line receive port, the pass indication, indicating the presence of valid receive signals or data, will be asserted. When pass is asserted, the signal detect threshold is lowered by about 60%, and all adaptive circuits are released from their quiescent operating conditions, allowing them to lock onto the incoming data. In 100BASE-TX operation, pass will be de- asserted when no signal is presented for a period of about 1.2us. In 10BASE-T operation, pass will be de- asserted whenever no Manchester data is received. In either case, the signal detect threshold will return to the squelched level whenever the pass indication is de-asserted. The pass signal is used internally to control the operation of the receive clock recovery. |
