MB15E03集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

■DESCRIPTION

The Fujitsu MB15E03 is serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz prescaler. A 64/65 or a 128/129 can be selected for the prescaler that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 3.5 mA typ. This operates with a supply voltage of 3.0 V (typ.).

Furthermore, a super charger circuit is included to get a fast tuning as well as low noise performance. As a result of this, MB15E03 is ideally suitable for digital mobile communications, such as GSM (Global System for Mobile Communications).

■FEATURES
