NINO ASIC CHARACTERISTICS Differential Threshold controlled via SPI DAC Set “minus” point at 1V Set “plus” from 1V to 2v5 Stretch is “on” ( off also works) Hysteresis is “on” (fixed) Differential impedance is set to 30ohms By PCB design and by external resistors External Test Pulse input Power 1V5 (output) 180mA 2V5 (DAC ref and NINO core) 280mA JOSE DA SILVA –CT-PPS TIMING ENGINEERING REVIEW /

NINO PRODUCTION AND PLANS We have now 6 NINO boards assembled Need to modify the resistors for test pulse Threshold adjust by potentiometers or DAC Tests in the lab to understand fully the NINO pulses and cabling effects Using Torch Readout system (C.Carpinteiro) Setup may later be used to qualify the HPTDC mezzanines (depends on Digitizer board availability) Understand effect of different SIPM input signal terminations JOSE DA SILVA –CT-PPS TIMING ENGINEERING REVIEW /
