Abstract
The CMS silicon microstrip tracker readout system is unprecedented in size, with over nine million channels. It is an analogue readout system, implemented using CMOS ASICs and linear, semiconductor laser transmitters which send pulse height data off-detector for digitisation and the first level of data processing. The basic components which define the architecture originated in R&D projects in the early 1990s and were crucial in allowing this system to be realised. The availability of several key technologies was critical to achieving the design preferences, and the components and technologies were utilised also to build the control and monitoring system and, later, to implement critical elements of other CMS sub-detector systems. The background to the technology choices and early development of the system is described and an attempt is made to draw some lessons which could be relevant for the future.
