CA1394E

Video Processing Overview

The Harris CA1394E is a monolithic integrated circuit designed for the low-level horizontal section of monochrome or color television receivers. It integrates a phase detector, oscillator, regulator, and pre-driver. The device accepts negative horizontal sawtooth input and features an internal shunt regulator with linear balanced phase detection. It offers preset hold control capability, variable output duty cycle, and adjustable DC loop gain.

• Designed for negative horizontal sawtooth input applications
• Features internal shunt regulator and linear balanced phase detector
• Provides preset hold control capability and variable output duty cycle

Video Processing Applications

• Low-level horizontal sections in monochrome television receivers
• Low-level horizontal sections in color television receivers

Video Processing Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package type and marking codes match original specifications. Check for radiation hardness requirements if applicable to military variants. Ensure compatibility with existing PCB layouts and thermal management systems before integration.

Video Processing Selection Notes

Select this component specifically for television horizontal deflection circuits requiring negative sawtooth input processing. Compare against CA1391E when positive input polarity is required instead. Evaluate thermal performance and static phase error characteristics against system stability requirements. Verify pin compatibility with industry standard 1394 types for direct replacement scenarios.

Video Processing Part Context

The CA1394E belongs to the Harris CA139x series of TV horizontal processors. It is electrically equivalent and pin-compatible with industry standard types 1391 and 1394 in similar packages. The device serves as a specialized solution for analog video signal processing within cathode ray tube display architectures.

Video Processing Replacement Considerations

The CA1391E is a compatible alternative offering identical electrical performance and pinout but configured for positive horizontal sawtooth input rather than negative.
