MB507
1.6GHz TWO MODULUS PRESCALER
1.6GHz TWO MODULUS PRESCALER
The Fujitsu MB507 is a 1.6GHz two modulus prescaler used with a frequency
synthesizer to form a Phase Locked Loop (PLL). It will divide the input frequency
by the modulus of 128/129 or 256/257 and has an output level of 1.6V peak to
peak on ECL level.

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.
