Manufacturer:SIEMENS Description:A transmit squelch circuit, which consists of a pulse threshold detector, a pulse width detector, and a pulse duration timer, is used to suppress noise, as well as crosstalk on the AUI cable. The squelch circuitry disables the transmit driver if the signal at TX+ or TX- is smaller than the pulse threshold. Pulse noise is rejected by a pulse width detector that passes only pulses with durations greater than 20 ns. The pulse duration timer disables the transmit driver if no pulses are received for two-bit periods following valid pulses. At the end of a transmission, the pulse duration timer disables the transmitter and triggers the blanking timer, used to block dribble bits. |
