... MB15F04 DESCRIPTION The Fujitsu MB15F04 is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 2.0GHz prescalers. A 64/ 128/129 for both 2.0GHz prescalers can be selected that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 11.0mA typ supply voltage of 3 ...

MB15F04 POWER SAVING MODE (Intermittent Mode Control Circuit) Setting a PS pin to Low, TX-PLL (RX-PLL) enters into power saving mode resultant current consumption can TX(RX) be limited to 0.1 A (typ.). Setting PS pin to High, power saving mode is released so that the device works normally. In addition, the intermittent operation control circuit is included which helps smooth start up from stand by mode. ...
