ASSP SERIAL INPUT PLL FREQUENCY SYNTHESIZER
MB1504/MB1504H/MB1504L
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.

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).
