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).

WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
s
RECOMMENDED OPERATING CONDITIONS
WARNING: Recommended operating conditions are normal operating ranges for the semiconductor device. All
the device's electrical characteristics are warranted when operated within these ranges.
Always yse semiconductor devices within the recommended operating conditions. Operation outside
these ranges may adversely affect reliability and could result in device failure.
