Universal I2c-bus Programmable Rf Modulator

The TDA8822 is a programmable Modulator which generates an RF TV channel from a baseband Video signal and a baseband Audio signal in the event of negative Video and FM sound standards (B/G, I, D/K, M and N standards). Two PLL frequency-synthesizers set the picture Carrier frequency and the sound subcarrier frequency to the required frequencies. These PLL frequency-synthesizers are programmed via the I 2C-bus. The I 2C-bus controls these features: Video modulation depth Sound subcarrier modulation deviation Picture-to-sound ratio. This makes the IC suitable for multistandard applications without any adjustment into the application. Additional features are provided like an input for the NICAM or second FM Carrier a test pattern signal generator with a LED Driver and a general purpose output port. By NXP Semiconductors
