MB1503
LOW-POWER PLL FREQUENCY SYNTHESIZER WITH
POWER SAVE FUNCTION (1.1GHz)
The Fujitsu MB1503 is a serial input phase-locked loop (PLL) frequency synthesizer with a
pulse-swallow function. A stand-by mode is provided to limit power consumption during
intermittent operation.
The MB1503 is configured of a 1.1GHz dual-modulus prescaler with 128/129 divide ratio,
control signal generator, 16-bit shift register, 15-bit latch, programmable reference divider
(binary 14-bit programmable reference counter), 1-bit switch counter, phase comparator
with phase conversion function, charge pump, crystal oscillator, 19-bit shift register, 18-bit
latch, programmable divider (binary 7-bit swallow counter and binary 11-bit programmable
counter), analog switches, and an intermittent operation control circuit that selects the
operating or stand-by mode depending on the power-save control input state (PS).
The MB1503 operates from a single +5 V supply. Fujitsu’s advanced technology achieves
an Icc of 8mA, typical. The stand-by mode current consumption is just 100µA.

NOTE:
Permanent device damage may occur if the above Absolute Maximum
Ratings are exceeded. Functional operation should be restricted to the
conditions as detailed in the operational sections of this data sheet. Exposure
to absolute maximum rating conditions for extended periods may affect device
reliability.
PLASTIC PACKAGE
(DIP-16P-M04)
This device contains circuitry to protect the inputs
against damage due to high static voltages or electric
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.
