The broad energy response, low electronic read noise, and good energyresolution have made X-ray Charge-Coupled Devices (CCDs) an obvious choice fordeveloping soft X-ray astronomical instruments over the last half century. Theyalso come in large array formats with small pixel sizes which make them apotential candidate for the next generation astronomical X-ray missions.However, the next generation X-ray telescopic experiments propose forsignificantly larger collecting area compared to the existing observatories inorder to explore the low luminosity and high redshift X-ray universe whichrequires these detectors to have an order of magnitude faster readout. In thiscontext, the Stanford University (SU) in collaboration with the MassachusettsInstitute of Technology (MIT) has initiated the development of fast readoutelectronics for X-ray CCDs. At SU, we have designed and developed a fast andlow noise readout module with the goal of achieving a readout speed of 5Mpixel/s. We successfully ran a prototype CCD matrix of 512 $\times$ 512 pixelsat 4 Mpixels/s. In this paper, we describe the details of the readoutelectronics and report the performance of the detectors at these readout speedsin terms of read noise and energy resolution. In the future, we plan tocontinue to improve performance of the readout module and eventually convergeto a dedicated ASIC based readout system to enable parallel read out of largearray multi-node CCD devices.
