FUJITSU SEMICONDUCTOR DATA SHEET DS04-21342-1E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F04 s DESCRIPTION The Fujitsu MB15F04 is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 2.0GHz prescalers. A 64/65 or a 128/129 for both 2.0GHz prescalers can be selected that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 11.0mA typ. at a supply voltage of 3.0V. Furthermore, a super charger circuit is included to provide a fast tuning as well as low noise performance. As a result of this, MB15F04 is ideally suitable for digital mobile communications. s FEATURES High frequency operation RX synthesizer : 2.0 GHz max. TX synthesizer : 2.0 GHz max. Low power supply voltage: VCC = 2.7 to 3.6 V Very Low power supply current : ICC = 11.0 mA typ. (Vcc = 3V) Power saving function : IPSTX = IPSTX = 10 A max. Serial input 14–bit programmable reference divider: R = 5 to 16,383 Serial input 18–bit programmable divider consisting of: - Binary 7–bit swallow counter: 0 to 127 - Binary 11–bit programmable counter: 5 to 2,047 On–chip high performance charge pump circuit and phase comparator, achieving high–speed lock–up and low phase noise Wide operating temperature: Ta = 40 to 85°C s PACKAGE 20-pin, Plastic SSOP (FPT-20P-M03) MB15F04 s PIN ASSIGNMENT (TOP VIEW) GNDRX1 OSCIN GNDTX nTX VccTX XnTX BSCTX PSTX DoTX BSTX 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 ……
