Prescaler with low current and low radiation
DS2219 - 2.4 The SP4666 is a selectable division ratio high speed divider capable of replacing separate fixed ratio ECL prescalers with a single part in applications with alternative 464 and 4256 division requirements. A switched low pass filter with 23dB points at 5·3MHz and 15·6MHz is connected before the output stage to reduce the harmonic content to a very low level.
