MB15F72UV Datasheet | Fujitsu Semiconductor Limited

DESCRIPTION The Fujitsu MB15F72UV is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1300 MHz and a 350 MHz prescalers. A 64/65 or a 128/129 for the 1300 MHz prescaler, and a 8/9 or a 16/17 for the 350 MHz prescaler can be selected for the prescaler that enables pulse swallow operation. The Bi CMOS process is used, as a result a supply current is typically 2.5 m A at 2.7 V. The supply voltage range is from 2.4 V to 3.6 V. A refined charge pump supplies well-balanced output current with 1.5 m A and 6 m A selectable by serial data. The data format is the same as the previous one MB15F02SL, MB12F72SP/UL. Fast locking is achieved for adopting the new circuit. MB15F72UV is in the new small package (BCC18) , which decreases a mount area of MB15F72UV about 50% paring with the former BCC20 (for dual PLL) . MB15F72UV is ideally suited for wireless mobile munications, such as CDMA. s FEATURES - High frequency operation : RF synthesizer : 1300 MHz Max : IF synthesizer : 350 MHz Max - Low power supply voltage : VCC = 2.4 V to 3.6 V - Ultra low power supply current : ICC = 2.5 m A Typ (VCC = 2.7 V, SWIF = SWRF = 0, Ta = +25 °C, in IF, RF locking state) (Continued) s PACKAGE 18-pin plastic BCC (LCC-18P-M05) ..
