NXP Semiconductors TDA8822
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). These PLL frequency-synthesizers are programmed via the I2C-bus. The I2C-bus controls these features: • Video modulation depth • Sound subcarrier modulation deviation • Picture-to-sound ratio.| Part No. | TDA8822 |
