Abstract :
A control and data acquisition system has been designed for the CDF Silicon Vertex Detector (SVX) at Fermilab. The system controls the operation of the SVX Rev D integrated circuit (SVX IC) that is used to instrument a 46000 microstrip silicon detector. The Fastbus Sequencer, a programmable timing generator for controlling the SVX Rev D integrated circuit is described along with the controller and digitizer modules that reside in SVX Rabbit crates. A method for providing timing patterns to the wedge that allows pulsewidth control to within 10 ns over a period of 1 mu s is presented. Diagnostics abilities that provide mechanisms for understanding data and timing integrity are discussed.<>
