There are separate VCOs and PLLs for TX and RX. > Now when I read the mail from Matt ( > http://lists.gnu.org/archive/html/discuss-gnuradio/2005-07/msg00035.html > ), what I see that there is a clock line difference of around 1 cm. > So, if I have two different frequency generator circuits for TX/RX & > RX2 ports, then do we still get this clock line difference?
