NTE1837
Integrated Circuit
TV Tuner Controller
Description:
The NTE1837 is a tuner controller integrated circuit in a 16鈥揕ead DIP type package containing functions
such as band switch, inverter, and low鈥損ass filter. This device can be used as a frequency synthesizer
or a voltage synthesizer, depending on the external application circuit.
