Abstract

We present two lines of ASICs dedicated to the control and readout of CCD sensors. The CABAC (Clocks And Biases ASIC for CCDs) provides all required bias voltages and clocks. The ASPIC (Analog Signal Processing Integrated Circuit) processes 8 CCD output channels: amplification, Correlated Double Sampling, conversion to differential signal. Both chips are highly configurable in order to fulfill a wide range of astronomical CCD readout needs, from fast readout of wide-field imaging arrays to slower speeds and higher gains for spectroscopy. Their sizes and temperature ranges allow to integrate them in-cryostat, close to the sensors, and they offer diagnostic capabilities to assist the integration. In addition to extensive stand-alone tests, these chips are integrated in the LSST REB (Raft Electronics Board), and have been tested driving the E2V prototype CCD for the LSST focal plane.
