Squelching Characteristics
The receive data pairs and the collision pairs should have the following squelch characteristics:
1. The squelch circuits are on at idle (with input voltage at approximately 0 V differential).
2. If an input is in squelch, pulse is rejected if the peak differential voltage is more positive than –175 mV, regardless of pulse width.
3. A pulse is considered valid if its peak differential voltage is more negative than –300 mV and its width, measured at –285 mV, is > 25 ns.
4. The squelch circuits are disabled by the first valid negative differential pulse on either the AUI receive data or collision pair.
5. If a positive differential pulse occurs on either the AUI receive data or collision pair > 175 ns, end of frame is assumed and squelch circuitry is turned on.
