I am having troubles getting the AD8108 to wakeup. Looks to be pretty strait forward... Where can I find the software that ships with the demo board? Or is there possibly some sample code available? I am using the part in parallel loading mode.
AD8109
Production
The AD8108/AD8109 are high speed 8 × 8 video crosspoint
switch matrices. They offer a -3 dB signal bandwidth greater than
250 MHz and channel switch times...

Thanks for the prompt reply. I actually just got the chip working the other day...
My main problems were my code and the operation of the UPDATE pin was a little confusing. While working on the code, I was primarily looking at the detailed internal drawing (Figure 4, Logic Diagram) to understand how the digital control worked. This view does not show the function of the UPDATE pin. In this diagram, it shows the CE pin qualifying CLK and RESET only. After some frustration, I noticed Figure 1 (Functional Diagram) and it shows CE as a qualifier to UPDATE also.
Anyway, if I would have compared both diagrams I would have been up and running fast.
Thanks. The switch appears to be working properly.
