5.2.9.4 Clock Network Manager Configuration
Each of the Divide Select banks contain output division selector and controller pins. There are four
ternary inputs used to control the 0Q[1:0], 1Q[1:0], 2Q[1:0], 3Q[1:0], 5Q[1:0], 7Q[1:0], and
FB_DS[1:0] output clock dividers, inverters, and enable controls. See Table 1 in the
UT7R2XLR816 Clock Network Manager Datasheet for output behavior resulting from each
combination of these pins.
The #Q_PS# pins are the bank output phase selectors. Depending on required skew these bits will
need to be set. These two ternary inputs are used to control the 0Q[1:0], 1Q[1:0], 2Q[1:0], 3Q[1:0],
5Q[1:0], 7Q[1:0], and FB_DS[1:0] output phase alignment. See Table 2 in the UT7R2XLR816
CNM Datasheet for output behavior output phase selections resulting from each combination of
these pins.
