MB1513
SERIAL INPUT PLL FREQUENCY SYNTHESIZER SERIAL INPUT PLL FREQUENCY SYNTHESIZER WITH POWER SAVING FUNCTIONS (1.1GHz) The Fujitsu MB1513 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 MB1513 is configured of a 1.1 GHz dual-modulus prescaler with selectable 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 parator 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 stand-by or operating mode depending on the power-save control input state (PS).
The MB1513 operates from a single +5 V supply. Fujitsu’s advanced process technology achieves an ICC of 8mA, typical. The stand-by mode current consumption is just 100µA.
