●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=–40C to +85C
