Description:

The NTE1538 is a multifunctional integrated Circuit in a 16–Lead DIP type package containing various functions required for synchronization, deflection of color television sets. This device has been developed 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:

Synchronizing Separation

Horizontal Oscillation

Vertical Drive

Vertical Blanking

Horizontal AFC

Vertical Oscillation

X–Ray Protection

Features:

Multifunctional and Compact

Minimum Number of Parts Required

Horizontal, Vertical Oscillators are Stable Against Variations in Ambient Temperature and Supply Voltage due to Small Warm–Up Drift.

Small Variation in Horizontal Oscillation Frequency

Good Linearity and Interlace because DC Bias at Vertical Output Stage is Subjected to Sampling Control within Retrace Time.

Vertical Blanking Pulse Width can be Set Freely According to Peripheral Parts
