NTE851 Integrated Circuit VHF/UHF Prescaler Description: The NTE851 is an integrated circuit prescaler in a 14–Lead DIP type package intended for use in TV frequency synthesis tuning systems over an input frequency range of 90 to 1000MHz. It performs division by 256 in he UHF mode and division by 64 in the VHF mode. The mode of operation can be selected by means of the bandswitch and the separate UHF and VHF input pins provided. The output is a complementary emitter–coupled stage with controlled slew rate for harmonic suppression. All input pins should be AC coupled to the appropriate input signal source. Because of high sensitivity, unbuffered coupling from the local oscillator is possible in most cases.
