RF_CTL_WORD
— Counter Reset mode resets R & N counters.
— IF charge pump current can be selected to high current(8X) or low current(1X) mode.
— In the Speedy_Lock mode, the OUT0 and OUT1 pins can be utilized as synchronous switches between active
low and tri-state. The Speedy_Lock mode activates the OUT0 and OUT1 pins to be connected to GROUND
with a low impedance(< 150
) while a high charge pump gain(
≥
8X) is selected and otherwise to the
TRISTATE.
— For using a programmable CMOS output, the CMOS output bit(W2[21]=L) should be activated and then the
desired logic level should be programmed with the control bits W2[19] for OUT0 and W2[20] for OUT1.
