DESCRIPTION
The Fujitsu MB15E03L 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 2.5 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, MB15E03L is ideally suitable for digital mobile communications, such as GSM(Global System for Mobile
Communications), PDC(800MHz)(Personal Digital Cellular).
