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).
