- Analog television receivers (CRT, LCD, and Plasma)
- Video monitors
- Set-top boxes
- Video recording devices
Features:
- Single-chip TV processor
- Integrated video processing functions (luminance and chrominance)
- Integrated audio processing functions (sound IF, audio amplifier)
- Deflection control circuitry (horizontal and vertical)
- On-screen display (OSD) controller
- Teletext decoder (optional)
Benefits:
- Reduces the number of components required in a TV receiver.
- Lowers the cost of manufacturing a TV receiver.
- Saves space on the printed circuit board (PCB).
- Simplifies the design and assembly of a TV receiver.
Technical Specifications:
The TDA6920A operates on a single supply voltage, typically 5V. It includes a comprehensive set of video processing functions, such as automatic gain control (AGC), automatic frequency control (AFC), and color decoding. The audio processing section incorporates a sound intermediate frequency (SIF) amplifier, a volume control, and a speaker driver. The deflection control circuitry generates the horizontal and vertical synchronization signals required to drive the CRT or flat-panel display. The on-screen display (OSD) controller allows for displaying menus and information on the screen. Infineon Technologies has designed the TDA6920A to meet the requirements of a wide range of analog television standards. The device's integrated features and compact size make it a competitive solution for TV manufacturers looking to reduce costs and improve performance.
