Power Saving Mode (Intermittent Mode Control Circuit)
Status Normal mode Power saving mode
intermittent mode control circuit reduces power consumption. setting low, device enters into power saving mode, reducing current consumption. Electrical Characteristics chart specific value. phase detector output, becomes high impedance. dual PLL, lock detector, shown Output Logic table. Setting high, releases power saving mode, device works normally. intermittent mode control circuit also ensures smooth startup when device returns normal operation. When returned normal operation, phase comparator output signal unpredictable. This because unknown relationship between comparison frequency (fp) reference frequency (fr) which cause major change comparaor output, resulting frequency jump increase lockup time. prevent major frequency jump, intermittent mode control circuit limits magnitude error signal from phase detector when returns normal operation. Notes When power (VCC) first applied, device must standby mode. must Power-ON.
Clock Data
(power saving mode) Power-ON serial data least after power supply becomes stable (VCC Release power saving mode (PSIF, PSRF "H") least later after setting serial data.
