Fujitsu MB1503
MB1503 is a serial input phase-locked loop (PLL) frequency synthesizer with a pulse-swallow function. 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... The MB1503 operates from a single +5 V supply.
