■ DESCRIPTION

The Fujitsu MB15E06 is serial input Phase Locked Loop (PLL) frequency synthesizers with a 2.5 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 8 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, MB15E06 is ideally suitable for digital mobile communications, such as GPS (Global Positioning System) , Wireless LAN, CATV (CAble TeleVision) etc.
