content: So I was looking into getting a high-speed digitizer (basically like a sound card, but with much wider bandwidth, often several MHz), and in my research have stumbled onto this chip, which appears to be a high-speed digitizer on a chip. It takes power, and crystal oscillator connection, and takes a the analog signal to be digitized into its analog port, and converts that signal to digital data that is sent to the PC over a USB connection (and said USB connection can also be used for sending control signals to the chip). It also has other optional connections, but it appears that the required connections are pretty easy to set up. However, I can't find anybody selling this chip, at least not on the first page of Google results even when the name of the chip is the search term. Does anybody here know of any online electronic component dealers that are selling the Mirics MSI2500? Only products I can find in Google search results are already assembled products (specifically SDR tuners) that use this chip as the ADC (analog to digital converter) and another chip as the tuning chip. I don't want to tune anything. I just want the high-speed digitizer functionality of the MSI2500 chip.

It certainly isn't in English, so I have no idea how to even sign up as a customer at the site. Can anybody suggest a site in English that sells these chips.

content: You might want to try contacting their sales. Unlike the Qualcomms & the like, such asian semiconductor companies are often surprisingly cooperative with samples (but be prepared to pay UPS shipping rates) and pricing, even for small projects.hmm, just assumed they would be some Taiwanese company. But could be anything; no contact info apart from email addresses... weird

content: You can still buy the expensive?http://www.funcubedongle.com/which I think uses it but I think if you're patient you might find a cheaper Logitec LDT-1S310U/J on yahoo Japan auctions. I'm not doing any more googling for you.
