A readout electronics has been developed for the silicon strip array detector system of HIRFL-CSR-ETF.It consists of 48 front end electronics(FEE)boards,12 PXI-DAQ boards and one trigger board.It can implement energy and time measurements of 4608 channels.Each FEE board is based on 6 ASICs(ATHED),which implements energy and time measurements of 96 channels.The PXI-DAQ board meets requirements of high-speed counting and amount of readout channels and can process signals of 4 FEEs.The trigger board is developed to select the valid events.The energy linearity of the readout electronics is better than 0.3%in the dynamic range of 0.1-0.7V.In the test with a standard triple alpha source,the energy resolution was 1.8%at 5.48 MeV.This readout electronics enables the silicon strip array system to identify particles of A<14.
