single pll frequency synthesizers with on-chip prescalers 24 fujitsu microelectronics, inc. functional descriptions power-saving mode (intermittent mode control) the intermittent mode control circuit greatly reduces the pll power consumption by shutting down various internal functions, depending upon the settings of the power-save (ps) pins. (see the electrical characteristics chart for the speci? value of current when the device is in the power-saving mode.) in this mode, the phase detector output, do, becomes high impedance. setting the ps pin high releases the power-saving mode, returning the selected pll to normal operation. the intermittent mode control circuit also ensures a smooth startup when the device returns to normal operation, at which time the phase comparator output signal is unpredictable due to the unknown relationship between the comparison frequency (fp) and the reference frequency (fr). this can cause a major change in the comparator output, resulting in a vco frequency jump and an increase in lock- up time. to prevent this the intermittent mode control circuit limits the magnitude of the error signal from the phase detector when it returns to normal operation. table 10. power save pin setting (ps pins) ps pins status h normal mode l power saving mode when power (v cc ) is first applied, the device must be in standby mode, ps = low, for at least 1s. on off v cc clock data le ps (1) (2) (3) t v 1 s t ps 100 ns (1) ps = l (power-saving mode) at power on (2) set serial data 1 ? later after power supply remains stable (v cc > 2.2v).
