ULTRA HIGH FREQUENCY PRESCALER
ULTRA HIGH FREQUENCY PRESCALER
The Fujitsu MB505 is a high frequency, up to 1.6GHz, prescaler used with a
frequency synthesizer to form a Phase Locked Loop (PLL). It will divide the input
frequency by the modulus of 128 or 256 and the output level is 1.6V peak to peak
on ECL level.
Operation in the 1.6GHz range meets the specification for applications in Direct
Broadcasting Satellite Systems (DBS), CATV systems, and UHF Transceivers.

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.
