On-Chip 2.0GHz Prescaler
MB15E05
The Fujitsu MB15E05 is serial input Phase Locked Loop (PLL) frequency synthesizers with a 2.0 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 6mA typ. This
operates with a supply voltage of 3.0V (typ.).
Furthermore, a super charger circuit is included to get a fast tuning as well as low noise performance. As a result of
this, MB15E05 is ideally suitable for digital mobile communications, such as PCN (Personal Communication Network),
PCS (Personal Communication Service), etc.
This device contains circuitry to protect the inputs against damage due to high static voltages or electroc fields. However, it is advised that normal precautions
be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit.
