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).
The MB1504 operates from a low supply voltage (3V typ) and consumes low power (30mW
at 520MHz).

This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields. How-
ever, it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum rated volt-
ages to this high impedance circuit.
