SP4660

3060-2.2 SP4660 1GHz4256 PRESCALER WITH LOW CURRENT AND LOW RADIATION The SP4660 4256 prescaler is one of GPS’ range of high speed dividers for consumer frequency synthesis and measurement systems. It has a low supply current, giving reduced dissipation and operating temperatures in an 8-pin plastic DIL package. Spurious radiation has been reduced from all stages. The SP4660 incorporates an on-chip preamplifier with differential inputs and has balanced ECL outputs.
