MB15F73UL Datasheet | Fujitsu Semiconductor Limited

DESCRIPTION The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250MHz and a 600MHz prescalers. A 64/65 or a 128/129 for the 2250MHz prescaler, and a 8/9 or a 16/17 for the 600MHz prescaler can be selected for the prescaler that enables pulse swallow operation. The latest Bi CMOS process is used, as a result a supply current is typically 3.2m A typ. at 2.7V. The supply voltage range is from 2.4V to 3.6V. A refined charge pump supplies well-balanced output current with 1.5m A and 6m A selectable by serial data. The data format is same as the previous one MB15F03SL, MB15F73SP. Fast locking is acheived for adopting the new circuit. The new package(BCC20) decreases a mount area of MB15F73UL more than 30% paring with the former BCC16(for dual PLL). MB15F73UL is ideally suited for wireless mobile munications, such as GSM and CDMA. n FEATURES - High frequency operation: RF synthesizer : 2250MHz max IF synthesizer : 600MHz max - Low power supply voltage: VCC = 2.4 to 3.6 V - Ultra Low power supply current : ICC = 3.2 m A typ.
