Functional Description (Continued)
PROGRAMMABLE MODES
Several modes of operation can be programmed with bits R16–R20 including the phase detector polarity, charge pump
TRI-STATE and the output of the F
oLD pin. The prescaler and powerdown modes are selected with bits N19 and N20. The
programmable modes are shown in
Table 1. Truth table for the programmable modes and F
oLD output are shown in Table 2 and
Table 3.

Note 9: Refer to POWERDOWN OPERATION in Functional Description.
Note 10: The ICPo LOW current state = 1/4 x ICPo HIGH current.
Note 11: PHASE DETECTOR POLARITY
Depending upon VCO characteristics, R16 bit should be set accordingly: (see figure right)
When VCO characteristics are positive like (1), R16 should be set HIGH;
When VCO characteristics are negative like (2), R16 should be set LOW.
