MB15A02

DS04–21321–1aE DATA SHEET MB15A02 ASSP SERIAL INPUT PLL FREQUENCY SYNTHESIZER LOW POWER SERIAL INPUT PLL SYNTHESIZER WITH 1.1GHZ PRESCALER The Fujitsu MB15A02, utilizing Bi-CMOS technology, is a single chip serial input PLL synthesizer with pulse-swallow function. The MB15A02 contains a 1.1GHz two modulus prescaler that can select either a 64/65 or 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 reverse function, charge pump, crystal oscillator, 19-bit shift register, 18-bit latch, and programmable divider (binary 7-bit swallow counter and binary 11-bit programmable counter). It operates supply voltage of 5V typ. and achieves very low supply current of 7mA typ. realized through the use of Fujitsu Advanced Process Technology. High operating frequency: fIN MAX=1.1GHz (PIN MIN=–10dBm) PLASTIC PACKAGE FPT-16P–M05 Pulse swallow function: 64/65 or 128/129 Low supply current: ICC=7mA typ. Serial input 18-bit programmable divider consisting of: – Binary 7-bit swallow counter: 0 to 127 – Binary 11-bit programmable counter: 16 to 2,047 Serial input 15-bit programmable reference divider consisting of: – Binary 14-bit programmable reference counter: 6 to 16,383 – 1-bit switch counter (SW) sets divide ratio of prescaler – On-chip charge pump (Bipolar type) – Output for external charge pump PLASTIC PACKAGE FPT-...
