Hello Glenn,
The Valon 5007 has two ADF4350, and are controlled using a TI MSP430
(UART-SPI bridge?). According to Patrick Brandt, the Linux drivers are
compatible with 5007, but I have not tried yet using the Python/C++
libraries.
Best,

Just noticed Valon has a new synthesizer module 5007 with very similar
output range to the ADF4350, but the photo is not high enough
resolution to see if that is indeed what's on there.
http://www.valontechnology.com/products.html I wonder if the NRAO
linux driver for Valon would work for this.
Dave, Valon does not give a jitter spec, they just point to online
phase noise to jitter calculations. I'll calculate it sometime later.

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
