www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21376-2E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F73UV s DESCRIPTION The Fujitsu MB15F73UV is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250 MHz and a 600 MHz prescalers. A 64/65 or a 128/129 for the 2250 MHz prescaler, and a 8/9 or a 16/17 for the 600 MHz prescaler can be selected for the prescaler that enables pulse swallow operation. The BiCMOS process is used, as a result a supply current is typically 3.2 mA 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 mA and 6 mA selectable by serial data. The data format is the same as the previous one MB15F03SL, MB15F73SP/UL. Fast locking is achieved for adopting the new circuit. MB15F73UV is in the new small package (BCC18), which decreases a mount area of MB15F73UV about 50% comparing with the former BCC20 (for dual PLL) . MB15F73UV is ideally suited for wireless mobile communications, such as CDMA and PCS. s FEATURES High frequency operation : RF synthesizer : 2250 MHz Max : IF synthesizer : 600 MHz Max Low power supply voltage : VCC = 2.4 V to 3.6 V Ultra low power supply current : ICC = 3.2 mA Typ (VCC = 2.7 V, Ta = +25 °C, SWIF = SWRF = 0 in IF/RF locking state) (Continued) s PACKAGES 18-pin plastic BCC (LCC-18P-M05) www.DataSheet4U.com MB15F73UV (Continued) Direct power saving function : Power supply current in power saving mode Typ 0...
