... 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, ...

... MB1503 Intermittent operation Intermittent operation limits power consumption by shutting down or starting the internal circuits according to their necessity. If device operation resumes uncontrolled, the error signal output from the phase comparator may exceed the limit due to an undefined phase relationship between the reference frequency (f To prevent this, an intermittent operation control circuit is provided to decrease the variation in the locking frequency by forcibly correcting the phase of both frequencies to limit the error signal output ...
