Pin Description ------ ------------------- In1 - input 1 for the strip detector ... In128 - input 128 for the strip detector Vana - analog supply current (150...200)uA, analog Nwell Vdig - digital supply voltage 2.5 V max, digital Nwell LE - common enable for the readout (together with Rphi2) Reset - switch to initialize the preamplifiers IS - switch to (dis)connect detectors IS2 - switch to (dis)connect the pipeline SR - switch for a self-read function RG - bias for the optional feedback transistor (over-writeable) R12 - switch for the optional feedback transistor CS - switch for the optional feedback capacitor (320 fF) Vthres - threshold voltage for digital inputs (over-writeable) RBIB - RBI complementary signal RBI - input of the readout shift register RPhi1 - clock 1 for the readout shift register RPhi2 - clock 2 for the readout shift register RBO - output of the readout shift register Aref - pedestal voltage for the analog outputs (over-writeable) Adum - output of the dummy channel (for the noise subtraction) Aout - main analog output Cal - calibration pulse SEB - enable sampling shift register (inverted) SBIB - SBI complementary signal SBI - input of the sampling shift register SPhi1B - SPhi1 complementary signal SPhi1 - clock 1 for the sampling shift register SPhi2B - SPhi2 complementary signal SPhi2 - clock 2 for the sampling shift register NULL - analog quasi-ground (preamp`s shifting) GND - common ground (analog and digital) and substrate
