Description :

November 1990 Edition 5.0 DATA SHEET MB1502 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. Plastic Package DIP-16P-M04 FEATURES • High operating frequency: fIN MAX=1.1GHz (VIN MIN=10dBm) • Pulse swallow function: 64/65 or 128/129 • Low supply current: ICC=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) OSCIN OSCOUT 1 2 3 4 5 6 7 8 (TOP VIEW) 16 ∅R 15 ∅P 14 Plastic Package FPT-16P–M06 Pin Assignment ABSOLUTE MAXIMUM RATINGS (See NOTE) RatIng Power Supply Voltage Output Voltage Open-drain Voltage Output Current Storage Temperature NOTE: VP Value –0.5 to +7.0 VCC to 10.0 fOUT Symbol VCC VP VOUT VOOP IOUT TSTG Unit V V V V mA _C VCC DO GND LD 13 BiSW 12 FC 11 LE 10 Data 9 Clock –0.5 to VCC +0.5 –0.5 to 0.8 ± 10 –55 to +125 fIN 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. 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.
