Hi everyone.
I attempted to use the CRYSTEK CVT32 TXCO  (a tiny SMD unit) and 
although it presents about 1V Pk-Pk to the input of U1, it doesn't 
seem to be enough since there is no output on pin 1 of U1.

Regarding U1, (in the interest of full disclosure), I am not using 
the LTC1485 (Digikey was out of stock) but the SN75LBC176P from Mouser.

I'll try adding a a 74AC14 as a buffer in between the output of the 
TCXO and  the input of U1 and in the meantime maybe someone can 
either shed some more light or suggest a better arranegment :)


Thanks
