Video Processing datasheet and documents for TEA2031A
Video Processing Overview
The TEA2031A is a specialized video integrated circuit manufactured by STMicroelectronics, designed for color television systems. It ensures frame rate modulated parabolic and keystone corrections to the horizontal deflection circuitry of 110° color TV sets. The component operates with an operating voltage up to 35V and a minimum voltage of 16V. It is housed in an 8-pin DIP package with through-hole mounting.
Video Processing Feature Summary
- Provides frame rate modulated parabolic correction for horizontal deflection
- Ensures keystone correction for 110° color TV sets
Video Processing Applications
- Horizontal deflection circuitry in color television sets
- East-West correction in video display systems
Video Processing Procurement Notes
The TEA2031A is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or valid replacement components. Ensure compatibility with legacy 110° color TV designs if sourcing from secondary markets.
Video Processing Selection Notes
This component is specific to legacy analog video applications requiring East-West correction. Selection should focus on verifying the 8-DIP package compatibility and voltage requirements (16V-35V) against existing circuit board layouts. Due to its obsolete status, direct replacements must be evaluated for pinout and functional equivalence.
Video Processing Part Context
The TEA2031A belongs to the TEA2031 series of video processing ICs. It is categorized under Video Deflector Circuit ICs and Analog Voltage devices. The part is historically associated with STMicroelectronics' lineup for consumer electronics, specifically targeting CRT-based television manufacturing standards.
Video Processing Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the part is discontinued, engineers must evaluate generic East-West correction circuits or modern digital alternatives that replicate the parabolic and keystone correction functions within the specified voltage range.
