The SAA4951 is a memory controller designed by Philips for high-end TVs using 2fH technology. The circuit provides all necessary write, read and clock pulses to control different field memory concepts. Furthermore, the drive signals for the horizontal and vertical deflection power stages are generated. The device is connected to a microcontroller via an 8-bit data bus. The controller receives commands via the I2C bus. Due to this fact the start and stop conditions of the main output control signals are programmable and the SAA4951 can be set in different function modes depending on the used TV-feature concept.
