Thanks.  I understand the offset part then.  Nothing happens if there
is no DC offset.  I want to simulate an FM signal coming from the
TVRX, so the TVRX output is 20MHz, I understand that I then need to
write 2952790016 to the FR_RX_FREQ_0 register in the phase_acc.  The
cordic will then multiply this input signal by a 20MHz cos and sine to
generate the I and Q channels.  I just need to generate an FM signal
and get it to 16-bits as previously described and send it to the
cordic with the phase value written to the freq register?
