Hi, I have a problem finding the right DSP for my purposes. The Situation is that I have a dspace System for analyzing and influencing the Power Quality of the current Grid(harmonics). The System does its job but the results are improvable. Due to reasons of quantization Noise and Antialias I need a System with ADC that have 24 bits resolution and at least 100 khz sample rate. I need 4 channels of these high resolution ADC. The Inputs should be differential, not single-ended. I calculate the harmonics from the ADC input by using Filters, PLL and FFT. The results shall be sent to the existing dspace system. unfortunately the system does only have an asynchronous serial Communication Interface(rs232,rs422,rs485). My Internet Search leads me to Audio specific DSP as c6713. I cant figure out if they are the right Choice. I do not really understand the Terms as MCASP and cant find the resolution. It sounds to me there are codecs used which do some coding of the input which is not my desire. I need the rare pcm stream. The DSP should be in an Evaluation Environment which makes fast Development possible. Programming is supposed to be done from scratch in c or with some fundamental DSP Bios and similar. The ti Site is annoying. In former times there was the parameter ADC in the DSP Overwiews but it has dissolved. Additionally the site doesn't work corrcetly at the moment(in germany). Any suggestions? thanks in advance Senfkuchen
