CA1391E

Video Processing Overview

The CA1391E 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 positive horizontal sawtooth input and features an internal shunt regulator. It is electrically equivalent and pin-compatible with industry standard types 1391.

Video Processing Feature Summary

• Integrates linear balanced phase detector and preset hold control capability
• Includes internal shunt regulator and variable output duty cycle
• Designed for pull-in and low thermal frequency drift performance

Video Processing Applications

• Low-level horizontal section of monochrome television receivers
• Low-level horizontal section of color television receivers

Video Processing Procurement Notes

Verify component authenticity against Harris Corporation specifications. Confirm package compatibility with legacy industry type 1391 designs. Ensure supply chain sources provide valid documentation for the CA1391E variant to guarantee electrical equivalence and pin compatibility.

Video Processing Selection Notes

Select this component for applications requiring a positive horizontal sawtooth input. It serves as a direct replacement for industry standard type 1391 devices. Consider its integration of oscillator and regulator functions when designing compact horizontal deflection circuits.

Video Processing Part Context

Manufactured by Harris Corporation, the CA1391E belongs to a family of TV horizontal processors. It is functionally identical to the CA1394E except for input polarity, supporting both positive and negative sawtooth inputs across the series.
