SERIAL INPUT PLL FREQUENCY SYNTHESIZER WITH 520MHz PRESCALER

**The Fujitsu MB1504/MB1504H/MB1504L, utilizing BI-CMOS technology, is a

single chip serial input PLL frequency synthesizer with pulse-swallow function.**

The MB1504 series contains a 520MHz two modulus prescaler that can select either 32/33 or 64/65 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 inverse function; charge pump; crystal oscillator; 19-bit shift register; 18-bit latch; and a programmable divider (binary 7-bit swallow counter and binary 11-bit programmable counter).

FEATURES

• High operating frequency: fIN MAX=520MHz (VIN MIN=0.20VP-P)
• On-chip prescaler
• Low power supply voltage: 2.7V to 5.5V (3.0V typ)
• Low power supply consumption: 30mW (3.0V, 520MHz 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
• 2 types of phase detector output
–On-chip charge pump (Bipolar type)
–Output for external charge pump
• Wide operating temperature: TA=–40℃ to +85℃
