The Fujitsu MB506 is a high frequency, up to 2.4GHz, 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
