SERIAL INPUT PLL FREQUENCY SYNTHESIZER WITH 1.1GHz PRESCALER

The Fujitsu MB1501/MB1501H/MB1501L, utilizing BI-CMOS technology, is a single chip serial input PLL frequency synthesizer with pulse-swallow function.

• High operating frequency: fIN MAX=1.1GHz (PIN MIN=0.20VP-P)
• On-chip prescaler
• Low power supply voltage: 2.7V to 5.5V (3.0V typ)
• Low power supply consumption: 45mW (3.0V, 1.1GHz operation)
• Serial input 18-bit programmable divider consisting of:
   Binary 7-bit swallow counter (Divide ratio: 0 to 127)
   Binary 11-bit programmable counter (Divide ratio: 16 to 2047)
• Serial input 15-bit programmable reference divider consisting of:
   Binary 14-bit programmable reference counter (Divide ratio: 8 to 16383)
   1-bit switch counter (SW) Sets divide ratio of prescaler
• 2types of phase detector output
   On-chip charge pump (Bipolar type)
   Output for external charge pump
• Wide operating temperature: TA=–40°C to +85°C
