The Fujitsu MB15E03SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz prescaler.
The 1.2 GHz prescaler has a dual modulus division ratio of 64/65 or 128/129 enabling pulse swallowing operation.
The supply voltage range is between 2.4 V and 3.6 V. The MB15E03SL uses the latest BiCMOS process, as a result, the supply current is typically 2.0 mA at 2.7 V. A refined charge pump supplies a well balanced output currents of 1.5 mA or 6 mA. The charge pump current is selectable by serial data.
MB15E03SL is ideally suited for wireless mobile communications, such as GSM.
