R/W

This bit allows for specification of the operating Nyquist zone.

0 = Nyquist zone specification disabled

1 = Nyquist zone specification enabled

2-0

NYQUIST ZONE

R/W

These bits specify the operating Nyquist zone for the analog

correction loop.

Set the NQ ZONE EN bit before programming these bits.

For example, at a 3-GSPS chip clock, first Nyquist zone is from

dc to 1.5 GHz, the second Nyquist zone is from 1.5 GHz to 3

GHz, and so on.

000 = First Nyquist zone (dc – fS / 2)

001 = Second Nyquist zone (fS / 2 – fS)

010 = Third Nyquist zone

011 = Fourth Nyquist zone
