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.
TheMB1504seriescontainsa520MHztwomodulusprescalerthatcanselecteither32/33
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).
TheMB1504operatesfromalowsupplyvoltage(3Vtyp)andconsumeslowpower(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.
Wide operating temperature: T =–40_C to +85_C
