Hi, I saw this new product from Analog Devices http://www.analog.com/en/clock-and-timing/pll-synthesizersvcos/adf4350/products/product.html which seems like it may be a good choice for a flexible sampling clock for CASPER projects. The evaluation board is cheaper than the Valon boards at $175 and provides almost arbitrary frequency coverage instead of predefined outputs around 500 and 1000 MHz. The phase noise spec looks as good or better than the Valon as well. One disadvantage is that it appears to be like other Analog Devices eval boards which provides a Windows only USB interface. However, I have gotten around this in the past using GPIO to interface directly to the SPI port on the part.
Any opinions? Glenn
