PicoZed SDR info

Question

I just noticed http://picozed.org/sdr Looks like the design is pretty far along. What is the schedule for releasing more info?

Hi JH, PicoZed SDR provides an on-board 40MHz crystal and an external clocking option for the AD9361 by using an analog multiplexor (ADG772). If an external oscillator is used, the frequency can vary between 10 MHz and 80 MHz. The selection between the two clock sources is under control of a Zynq PL pin in Bank 34 (K11). The external clock signal is provided by a custom carrier board through the micro headers on the bottom of the SOM. As such, the same clock can be routed to the Zynq device if syncrhonization between BBP and RF devices is required. Hope that helps. -Matt
