MC12066

Order this document by MC12066/D 1.3 GHz Prescaler The MC12066 is a selectable divide by 64/256 prescaler. Typical frequency synthesis applications include electronically tuned TV/CATV and communication systems as well as instrumentation. The MC12066 is pin and functionally compatible to the Plessey SP4666, but with significantly lower power consumption. An internal, two stage preamplifier is included which isolates the differential inputs and provides gain for the input signal. Differential outputs are provided. The MC12066 contains an internal low pass filter to reduce harmonic content to a low level. The filter bandwidth is selectable depending on the state of the SEL pin. The typical –3.0 dB bandwidth is 4.3 MHz for ÷256 mode, and 17.2 MHz for ÷64 mode. Figures 2 and 3 illustrate typical device performance. 1.3 GHz Toggle Frequency Operating Supply Voltage of 2.7 to 5.5 V Low–Power 7.5 mA Typical at VCC = 5.0 V High Input Sensitivity, 5 mVrms Max at VCC = 2.7...
