SERIAL INPUT PLL FREQUENCY SYNTHESIZER
SERIAL INPUT PLL FREQUENCY SYNTHESIZER
WITH 1.1GHz PRESCALER
The Fujitsu MB1501/MB1501H/MB1501L, utilizing BI-CMOS technology, is a
single chip serial input PLL frequency synthesizer with pulse-swallow function.
The MB1501 series contain a 1.1GHz two modulus prescaler that can select either
64/65 or 128/129 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; programmable
divider (binary 7-bit swallow counter and binary 11-bit programmable counter).
The MB1501 operates on a low supply voltage (3V typ) and consumes low power
(45mW at 1.1GHz).

This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields. However, it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum rated voltages to this high impedance circuit.
Permanent device damage may occur if the above Absolute Maximum Ratings
are exceeded. Functional operation should be restricted to the conditions as
detailed in the operational sections of this data sheet. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

FUNCTIONAL DESCRIPTIONS
SERIAL DATA INPUT
Serial data input is input using 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 shifts one bit of the data into the internal shift registers.
When load enable (LE) is high level (or open), data stored in shift resisters is transferred to 15-bit latch or 18-bit latch depending upon
the control bit level.
Control data “H” ; Data is transferred into 15-bit latch.
Control data “L” ; Data is transferred into 18-bit latch.
PROGRAMMABLE REFERENCE DIVIDER
Programmable reference divider consists of 16-bit shift register, 15-bit latch and 14-bit reference counter. Serial 16-bit data format is
shown below.
