NTE1539規(guī)格書詳情

Description:

The NTE1539 is a multifunctional integrated circuit which is based on the internal circuit of the NTE1538. It incorporates various functions required for synchronization and deflection circuits of color television sets and especially aims at increasing the detections accuracy of the X–ray protection circuit. The ground pins for horizontal and vertical are provided separately to enable the easy layout of the printed circuit board.

The NTE1539 differs from the NTE1538 in the following points:

The output circuit of synchronizing separation is emitter follower type

The X–ray protection circuit is differential dual inouts thyristor system

The ground pins for horizontal and vertical are provided separately.

Functions:

Synchro Separator

Horizontal AFC

Vertical Driver

Vertical Blanking Pulse Making

Horizontal Oscillator

Vertical Oscillator

X–Ray Protector

Features:

Multifunctional and Small–Size

Minimum Number of Parts Required

Horizontal and Vertical Oscillators being Stable to Variation of Ambient Temperature and Supply Voltage Owing to Small Warming–Up Drift.

Small Variation of Horizontal Oscillation Frequency

Good Linearity and Interface Owing to DC Bias at Vertical Output Stage being Sampling Controlled within Retrace Time.

Vertical Blanking Pulse Width being Freely Set Up According to Peripheral Parts.

High Detection Accuracy of X–Ray Protection Circuit.
