Power Saving Mode (Intermittent Mode Control Circut)
Status Normal mode Power saving mode PSTX/PSRX pins
intermittent mode control circuit reduces power consumption. setting pins 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 pins 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 comparator 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, PSTX PSRX Low, least pins must Power-ON
Clock Data PSTX PSRX
PSTX PSRX (power saving mode) Power-ON serial data least after power supply becomes stable (VCC Release power saving mode (PSTX, PSRX "H") least after setting serial data.
