Tom, If you are building your own board - I have used this part:
SN74LVC1G125 - Single Bus Buffer Gate with 3-State Output and it is suitable for the job. I have measured the performance of the logic family - and what I observed follows what is in the spec sheets from TI. I did not officially record my measurements as I didn't do the testing on precision, calibrated equipment. But I did do all testing at 10MHz and I did also look at the 1PPS signal of course. I have used other parts in this logic family from TI and have had good results at these frequencies. 73's, John AJ6BC On Thu, Sep 26, 2013 at 1:22 PM, Bob Bownes <[email protected]> wrote: > TV video distribution amps work very nicely.
