Product data sheet
Table 19:
These bits force the inputs of the second loop charge pump. This test could be used to force the LO
VCO at its maximum or minimum tuning voltage.
Table 20:
Table 21:
These bits control the amplitude of the internal LC VCO.
Table 22:
Bit PORT1 controls the use of PORT1 and bit PORT0 controls the use of PORT0. Outputs PORTn
are realized with open-drain NMOS transistors.
Table 23:
This bit controls the duration of the wait time of the calibration. This time is used to wait PLL locking
after programming a Dword. The reference clock of the time is the comparison frequency of the PLL
Table 24:
These bits control the voltage threshold for the ACUP comparator. The ACUP and ACDN
comparators sense the LC VCO tuning voltage at pin VT.
