System Electronics and DAQ for the Silicon Vertex Detector Upgrade for PHENIX

The PHENIX experiment at RHIC will be upgraded with a silicon vertex detector (VTX). The VTX is comprised of 4 barrels of silicon detectors. The inner two barrels will be implemented with pixel detectors read out using the ALICE1LHCb readout chip. The pixel detectors and readout chips are mounted on a high density interconnect (PIXEL bus) allowing data to be read out at 10 MHz. The outer two barrels will be implemented with a novel stripixel sensor designed by the Brookhaven National Laboratory Instrumentation Division. Each stripixel sensor will be instrumented with 12 SVX4 readout chips and controlled by a custom ASIC designed at Oak Ridge National Laboratory allowing for high speed read out. We will report of the design and status of the read out and Data Acquisition system for PHENIX VTX detector.
