NTE1538
Integrated Circuit
TV Horizontal/Vertical OSC Driver
Description:
The NTE1538 is a multifunctional integrated circuit in a 16鈥揕ead DIP type package containing various
functions required for synchronization, deflection of color television sets. This device has been devel-
oped under the design concept that the basic characteristics should be made more complete and the
television sets incorporating the NTE1538 should be streamlined by making the device compact and
by minimizing the number of parts required.
Functions:
D
Synchronizing Separation
D
Horizontal Oscillation
D
Vertical Drive
D
Vertical Blanking
D
Horizontal AFC
D
Vertical Oscillation

X鈥揜ay Protection
Features:
D
Multifunctional and Compact
D
Minimum Number of Parts Required
D
Horizontal, Vertical Oscillators are Stable Against Variations in Ambient Temperature and Supply
Voltage due to Small Warm鈥揢p Drift.
D
Small Variation in Horizontal Oscillation Frequency
D
Good Linearity and Interlace because DC Bias at Vertical Output Stage is Subjected to Sampling
Control within Retrace Time.
D
Vertical Blanking Pulse Width can be Set Freely According to Peripheral Parts
