Figure 2. Delay Range and POL Bit vs DIVCODE
If the voltage is generated by other means (i.e., the output
of a DAC) it must track the V+ supply voltage. The last
column in Table 1 shows the ideal ratio of VDIV to the
supply voltage, which can also be calculated as:
VDIV
V+
=
DIVCODE

Forexample,ifthesupplyis3.3VandthedesiredDIVCODE
is 4, VDIV = 0.281 3.3V = 928mV ± 50mV.
Figure 2 illustrates the information in Table 1, showing
that NDIV is symmetric around the DIVCODE midpoint.
