5 GHz Prescaler MB15E07SR ■ 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.
