Abstract:
A trigger circuit generates a trigger signal when a differential input signal crosses a differential threshold voltage level. A first side of the differential input signal is applied to a first terminal of a first load termination resistor. A second side of the differential signal is applied to a first terminal of a second load termination resistor. A first side of the differential threshold voltage level is applied to a second terminal of the first load termination resistor. A second side of the differential threshold voltage level is applied to a second terminal of the second load termination resistor. A comparator generates the trigger signal when a voltage level at the first terminal of the first resistor exceeds a voltage level at the first terminal of the second resistor.
