Abstract
PACIFIC is a 64 channel mixed-signal ASIC designed for the scintillating fiber tracker readout
and developed for the LHCb upgrade in 2019/20. It connects without any extra components to
the 128 channel double-die SiPM arrays sensing the fibres output signal. The analog processing
chain begins with a current conveyor followed by a tunable fast shaper and a gated integrator.
The signal is digitized with three configurable discriminators at 40MHz. The results of every
four channels are encoded to two bits per channel, serialized and transmitted at 320MSa/s over a
differential SLVS data link. PACIFIC has been designed using a 130nm CMOS technology and
power consumption kept below 10mW/channel.
