ENCODE INPUT PARAMETERS Maximum Encode Rate Full VI 105 MSPS Minimum Encode Rate Full IV 20 MSPS Encode Pulse Width High (tEH) Full IV 3.8 ns Encode Pulse Width Low (tEL) Full IV 3.8 ns Aperture Delay (tA) 25°C V 2 ns Aperture Uncertainty (Jitter) 25°C V 3 ps rms DIGITAL OUTPUT PARAMETERS Output Valid Time (tV)1 Full VI 2.5 ns Output Propagation Delay (tPD)1 Full VI 4.5 6 ns Output Rise Time (tR) 25°C V 1.0 ns Output Fall Time (tF) 25°C V 1.2 ns Out-of-Range Recovery Time 25°C V 5 ns Transient Response Time 25°C V 5 ns Recovery Time from Power-Down 25°C V 10 Cycles Pipeline Delay Full IV 5 Cycles 1 tV and tPD are measured from the 1.5 level of the ENCx input to the 50%/50% levels of the digital outputs swing. The digital output load during test must not exceed an ac load of 5 pF or a dc current of ±40 µA. Rise and fall times are measured from 10% to 90%.
