[Hackrf-dev] 10MHz clock

[Karl Koscher]

According to the HackRF schematic, CLKIN expects a 10 MHz, 3.3V CMOS
signal. According to http://www.perdrix.co.uk/FrequencyDivider/, the
Thunderbolt has a 2.5V peak-to-peak AC signal, so it needs to be run
through a clock shaper to drive the HackRF.

But this is just a guess.
