Phase Detector Polarity
Depending on VCO characteristics, R16 bit should be set as follows :
VCO characteristics are positive like (1) : R16 HIGH
VCO characteristics are negative like (2) : R16 LOW
foLD (Pin10) Output Truth Table
— When the PLL is locked and a lock detect mode is selected, the foLD output is HIGH, with narrow pulses
LOW.
— Counter Reset mode resets R & N counters.
— The high speed lock mode sets the foLD output pin to be connected to ground with a low impedance
(
≤
110
).
