MB15E06SR - Single Serial Input PLL Frequency Synthesizer On-chip 3.0 GHz Prescaler

General Description

The Fujitsu MB15E06SR is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 3.0 GHz prescaler. The 3.0 GHz prescaler has a dual modulus division ratio of 64/65 or 128/129 enabling pulse swallowing operation.

The MB15E06SR uses the BiCMOS process, as a result, the low phase noise achieved. The phase noise MB15E06SR was drastically improved comparing with the former single PLL, MB15E06. A refined charge pump supplies well-balanced output currents of 4.0mA.The supply voltage range is between 2.7 V and 4.0 V.

The data format of serial data and the pin assignments exept for ?P and ?R pins are same as the former one, so it is easy to replace the former one. MB15E06SR is ideally suited for the ETC (Electronic Toll Collection).
