SERIAL INPUT PLL FREQUENCY SYNTHESIZER
LOW POWER SERIAL INPUT PLL SYNTHESIZER
WITH 1.1 GHz PRESCALER
The Fujitsu MB1502, utilizing BI-CMOS technology, is a single chip serial input PLL
synthesizer with pulse-swallow function. The MB1502 contains a 1.1GHz two
modulus prescaler that can select of 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 conversion 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) and analog switch to speed up lock up time.
It operates supply voltage of 5V typ. and achieves very low supply current of 8mA typ.
realized through the use of Fujitsu Advanced Process Technology.
FEATURES
• High operating frequency: f_{IN MAX}=1.1GHz (V_{IN MIN}=10dBm)
• Pulse swallow function: 64/65 or 128/129
• Low supply current: I_CC=8mA typ.
• Serial input 18-bit programmable divider consisting of:
— Binary 7-bit swallow counter: 0 to 127
— Binary 11-bit programmable counter: 16 to 2047
• Serial input 15-bit programmable reference divider consisting of:
— Binary 14-bit programmable reference counter: 8 to 16383
— 1-bit switch counter (SW) sets divide ratio of prescaler
• On-chip analog switch achieves fast lock up time
• 2 types of phase detector output
— On-chip charge pump (Bipolar type)
— Output for external charge pump
• Wide operating temperature: –40_C to +85_C
• 16-pin Plastic DIP Package (Suffix: —P)
16-pin Plastic Flat Package (Suffix: —PF)

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.
