[time-nuts] Easy-to-use TDC to compare PPS

Hi,

I'd like to do some PPS comparisons on an SBC (like a Beaglebone or RPi) 
using a TDC. So far the ones I've seen which could be suitable are 
ACAM's TDC-GPX and TI's THS788:

http://www.ti.com/lit/ds/symlink/ths788.pdf

However these chips don't look so simple to connect to a standard SBC. 
Would anyone of you already have attempted that journey, or simply have 
a reasonably good idea about how to do that ?

Thanks,

     Xav
