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).

FUNCTIONAL DESCRIPTIONS
SERIAL DATA INPUT

Serial data input is input using the Data pin, Clock pin and LE pin. The 15-bit programmable reference divider and 18-bit programmable divider are
controlled, respectively.

On rising edge of the clock, one bit of the data shifts into the internal shift registers.

When load enable (LE) is high level (or open), data stored in the shift registers is transferred to the 15-bit latch or 18-bit latch depending upon the control bit
level.

Control data “H” : Data is transferred into the 15-bit latch.

Control data “L” : Data is transferred into the 18-bit latch.

PROGRAMMABLE REFERENCE DIVIDER

The programmable reference divider consists of a 16-bit shift register, 15-bit latch and 14-bit reference counter. Serial 16-bit data format is shown below.
