| Sept. 1995 Edition 3.0a DATA SHEET MB508 2.3GHz TWO MODULUS PRESCALER 2.3GHz TWO MODULUS PRESCALER The Fujitsu MB508 is a 2.3GHz two modulus prescaler used with a frequency synthesizer to form a Phase Locked Loop (PLL) and divides the input frequency by a modulus of 128/130, 256/258 or 512/514. The output level is 1.6V peak to peak ECL level. The ultra high frequency operation provides wide application, such as Direct Broadcasting Satellite System, CATV system, UHF Transceiver, etc. FEATURES S S S S S S S S High Frequency Operation: Input Signal Amplitude: Pulse Swallow Function: Power Dissipation: Wide Operation Temperature: Stable Output Amplitude: f = 2.3GHz max. (PIN = -4dBm min.) VIN = 100mVp-p (fIN = 100MHz to 1.8GHz) 128/130, 256/258, 512/514 120mW typ. -40C to +85C VOUT = 1.6Vp-p typ.

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.
