Just checked with Diligent.
They say: With sync capture you can specify any DIO or DIN pin to use as the sampling clock and enable . For the clock you can specify the edge (rising,falling,either) and for enable, the polarity.
On the Analog Discovery 2, this works reliably at up to 40MHz clock (mainly due to clock jitter). On the Digital Discovery it'll sample at up to 800MHz but it's really only reliable at up to 100MHz in synch mode.
