Abstract

This paper evaluates the performance of a low noise, high throughput readout system for X-ray Charge Coupled Devices (CCDs). High pixel throughput (>0.5M pixels per second) can be achieved by two methods that are not mutually exclusive. Firstly, sections of the CCD image can be read out in parallel from multiple output nodes incorporated in modern CCDs. Pixel read times can also be reduced to the minimum value where the sampling circuitry can process pixel data at an acceptable noise level. To this end, two Application Specific Integrated Circuits (ASICs) were designed to process multiple video channels at high pixel rates. The ASIC presented in this paper employs a 4-channel Correlated Double Sampler (CDS) ASIC and is evaluated for noise performance and inter-channel crosstalk. Here we discuss the ASIC specification, design, application and measured performance.
