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
90 MHz @VDD = 1.0 to 1.5V
120 MHz @VDD = 1.2 to 1.5V
• Separate power supply : 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.
