What is the mapping between the signal detect threshold voltage (Vth) and the setting in the Stratix IV GX ALTGX megawizard? - What is the mapping between the signal detect threshold voltage (Vth) and the setting in the Stratix IV GX ALTGX megawizard? Description The mapping between the signal detect threshold voltage (Vth) and the setting in the Stratix® IV GX ALTGX MegaWizard™ is detailed in the table below. ALTGX Setting Threshold Voltage (Vth) 8 50mV 7 45mV 6 40mV 5 35mV 4 30mV 3 25mV 2 20mV 1 15mV The rx_signaldetect status signal will assert when the receiver peak-to-peak differential input voltage VID(p-p) is higher than Vth multiplied by 4. Resolution This information will be added to a future release of the Stratix IV handbook.
