MB1503 Datasheet Low-power Pll Frequency Synthesizer

Manufacturer: Fujitsu Semiconductor Limited

Overview: .. Sept. 1995 Edition 1.0a DATA SHEET 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 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 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.
