■ DESCRIPTION
The Fujitsu MB15E07SR is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.5 GHz
prescaler. The 2.5 GHz prescaler has a dual modulus division ratio of 32/33 or 64/65 enabling pulse swallowing
operation.
The supply voltage range is between 2.7 V and 5.0 V. A refined charge pump supplies well-balanced output
currents of 1.0 mA and 4.0 mA. The charge pump current is selectable by serial data.
The phase noise of MB15E07SR was drastically improved comparing wuth the former single PLL, MB15E07SL.
The data format of serial data and the pin assignments except for φP, φR and OSCout pins are same as the former
one, so it is easy to replace the former one.
MB15E07SR is ideally suited for the base station of GSM (Global System for Mobile Communications) and PCS.
■ FEATURES
