... MB15E03 DESCRIPTION The Fujitsu MB15E03 is serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz prescaler. A 64/ 128/129 can be selected for the prescaler that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 3.5 mA typ. This operates with a supply voltage of 3 ...

... MB15E03 When designing a synthesizer, the FC pin setting depends on the VCO and LPF characteristics. : When the LPF and VCO characteristics are similar to (1), set FC bit high. : When the VCO characteristics are similar to (2), set FC bit low. PLL LPF 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 (max ...
