Ron, As far as part counts are concerned. For a given job, there are many different ways the job can be performed. There are also many factors to be considered when calculating costs. In many of my designs, one high density chip can cost many times more than the discrete logic needed to perform the same function. If there is board space to spare, it is then "cheaper" to use more components. If, on the other hand, board space is at a premium, the high density chip becomes "cheaper". Board size, component costs, manufacturability, component availability, and many other things all contribute to the cost equasion. Trying to equate part counts to product costs seldom works well. Given all the above, even trying to compare the 2090 and the Cltd boards is wasted effort. They were each designed to do different jobs, the Cltd to provide a low cost HD interface, and the 2090 to provide a flexible, highly optioned HD interface providing a DMA interface. I find it interesting to note that from the messages I've read here, both solutions come very close to each other in final system cost, depending of course on what the exact setup is. -Dean
