At Rutherford Appleton Laboratory, in collaboration with University of
California - Santa Cruz and the University of Oxford, we were involve
d in the design and development of the digital readout schemes for the
front end of the silicon strip detector at SDC. As a result of our wo
rk, we have designed and built a 128 channel integrated circuit to buf
fer hit patterns and to transmit them out of the detector module. This
integrated circuit is referred to as DDR2RH (Digital Data Read-out Ra
diation Hardened Version)
