Sept. 1995 Edition 3.0a Copyright 1990 by FUJITSU LIMITED and FUJITSU MICROELECTRONICS, INC. MB509 TWO MODULUS PRESCALER WITH ST AND-BY MODE TWO MODULUS PRESCALER WITH STAND-BY MODE The Fujitsu MB509 is a low power, two modulus prescaler equipped with the standby mode. The MB509 is used in conjunction with a frequency synthesizer to form a Phase Locked Loop (PLL) and will divide the input frequency by the modulus of 65/65 or 128/129. Power consumption is typically 11.5mA at 5.0V. under normal operation, with the current reduced to180µA in standby mode. By using MB509 with the MB87076, intermittent operating mode can be achieved.
FEATURES
High Frequency Operation: fmax = 1.1GHz max. (PIN = –4dBm min.) Pulse Swallow Function: 64/65, 128/129 Power Supply Consumption: 58mW typ. Stand-by Current: 180µA typ. Stable Output Amplitude: VO = 1.6Vp–p typ. Complete PLL synthesizer circuit with the Fujitsu MB87076, PLL frequency synthesizer IC Plastic 8-pin Dual-In-Line Package (Suffix: –P) Plastic 8-pin Mini Flat Package (Suffix: –PF) Built-in a Termination Resistor Stable output amplitude is obtained up to output load capacitance of 8pF ABSOLUTE MAXIMUM RA TINGS (See Note) Rating Symbol Value Unit Power Supply Voltage VCC –0.5 to +7.0 V Input Voltage VIN –0.5 to VCC V Output Current IO 10 mA Storage Temperature TSTG –55 to +125 °C Note: 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. PLASTIC PACKAGE FPT-08P-M01 PIN ASSIGNMENT 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.
