s DESCRIPTION
The Fujitsu MB15C03 is a serial input Phase Locked Loop (PLL) frequency synthesizer with a prescaler. A 64/ 65 division is available for the prescaler that enables pulse swallow operation. This operates with a supply
voltage of 1.0 V (min.). MB15C03 is suitable for mobile communications, such as paging systems.
s FEATURES
Frequency operation Separate power supply : 90 MHz @VDD = 1.0 to 1.5V 120 MHz @VDD = 1.2 to 1.5V VDD = 1.0 to 1.5 V (for overall system) VP = 2.0V to 3.5V (for a charge pump)
Power saving function Pulse swallow function: 64/65 Serial input 14-bit programmable reference divider: R = 5 to 16,383 Serial input 18-bit programmable divider consisting of: - Binary 6-bit swallow counter: 0 to 63 - Binary 12-bit programmable counter: 5 to 4,095 Wide operating temperature: Ta = –20 to +60°C Plastic 16-pin SSOP package (FPT-16P-M05)
s PACKAGE
16-pin, plastic SSOP
(FPT-16P-M05)
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.
