Integrated Circuit
TV Tuner Controller
Description:
The NTE1837 is a tuner controller integrated circuit in a 16–Lead DIP type package containing functions
such as band switch, inverter, and low–pass filter. This device can be used as a frequency synthesizer
or a voltage synthesizer, depending on the external application circuit.
Functions:
D Band Switch (Equivalent to the NTE1658: Refer to the Truth Table)
D Inverter
D Low–Pass Filter (Voltage Follower, Operational Amplifier)
Features:
D 2–Input, 5–Output Band Switch
D Band Switch (NTE1658) Available by Changing Over C Pin
D High Maximum Output Current, Low Saturation Voltage
D Meet CATV Tuner Requirements
D Frequency Synthesizer or Voltage Synthesizer Application depending on Inverter and
Operational Amplifier Connections
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
