The TDA933xH series is a TV display processor controlled by the I2C bus, which can be used in both single scan (50 or 60 Hz) and double scan (100 or 120 Hz) applications.
The document provides a complete description of the TDA933xH series TV display processors, including functional features such as single‑scan/double‑scan operation, YUV and RGB inputs, black‑current stabilization, and programmable deflection processing. It also lists the pin configuration for the 44‑pin QFP package and the I2C‑bus control interface.
Technical data are given in a quick‑reference table, covering supply voltage, input signal levels, output amplitudes, and current specifications. Additional sections describe the RGB control circuit, output amplifier, synchronization and deflection processing, and notes on operation and status bits.
