Central Silicon Tracker of H1.
Figure: p-side of the hybrid made from
635 m . Left: Five preamplifier chips (APC128). Low center: Decoder Chip.
Figure: Schematic layout of
the electrical and optical readout and control.
Figure: Simplified diagram of APC128 chip.
Figure: Layout of Decoder Chip.
Figure: Circuit diagram of the input stages
of the decoder chip. The capacitors are external to the decoder chip.
Figure: Circuit diagram of the electrical-optical
converters. Left: Analog signal driver situated on the hybrid (with the exception of the
LED). Power consumption 50 mW. Right: Digital signal driver
situated 34 m apart from the detector.
Figure: Circuit diagram of the optical-electrical
converters. Left: Analog signal receiver situated 34 m
apart from the detector. Right: Digital signal receiver situated
on a printed circuit at the end of the detector. Power consumption 250
mW.
Figure: Distribution of measurements of a
reference voltage (2V) transmitted
through the optical readout chain and digitised
with a 12 bit FADC. The distribution is purely Gaussian with an r.m.s of 2.9
bits. For comparison: Signals from the APC128 have a noise contribution of 32
bits.

enlarged view of the central part with fibers glued in (right).
