2.0 Programming Description (Continued)
2.6.2 PD_POL Main
MAIN SYNTHESIZER PHASE DETECTOR POLARITY
Main R[17]
The PD_POL Main bit is used to control the Main synthesizer’s phase detector polarity based on the VCO tuning characteristics.

2.6.4 TRI-STATE ID
o Main
MAIN SYNTHESIZER CHARGE PUMP TRI-STATE CURRENT
Main R[19]
The TRI-STATE ID
o Main bit allows the charge pump to be switched between a normal operating mode and a high impedance
output state. This happens asynchronously with the change in the TRI-STATE ID
o Main bit.
Furthermore, the TRI-STATE ID
o Main bit operates in conjuction with the PWDN Main bit to set a synchronous or an
asynchronous powerdown mode.
