Both the internal charge pump output level (DO) and the phase comparator output (φR, φP) are reversed according to the FC bit. Also, the monitor pin (fOUT) output is controlled by the FC bit. The relationship between the FC bit and each of DO, φR, and φP is shown below.

Power Saving Mode (Intermittent Mode Control Circuit) Setting a PS pin to Low, the IC enters into power saving mode resultatly current sonsumption can be limited to 10 µA (max.) . Setting PS pin to High, power saving mode is released so that the IC works normally. In addition, the intermittent operation control circuit is included which helps smooth start up from the power saving mode. In general, the power consumption can be saved by the intermittent operation that powering down or waking up the synthesizer. Such case, if the PLL is powered up uncontrolled, the resulting phase comparator output signal is unpredictable due to an undefined phase relation between reference frequency (fr) and comparison frequency (fp) and may in the worst case take longer time for lock up of the loop. To prevent this, the intermittent operation control circuit enforces a limited error signal output of the phase detector during power up, thus keeping the loop locked. During the power saving mode, the corresponding section except for indispensable circuit for the power saving function stops working, then current consumption is reduced to 10 µA (max.) . Note : • While the power saving mode is executed, ZC pin should be set at “H” or open. If ZC is set at “L” during power saving mode, approximately 10 µA current flows. • PS pin must be set “L” at Power-ON. • The power saving mode can be released (PS : L → H) 1 µs later after power supply remains stable. • During the power saving mode, it is possible to input the serial data.
