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).
