NXP Semiconductors TDA8752B
The TDA8752B is a triple 8-bit ADC with controllable amplifiers and clamps for the digitizing of large bandwidth RGB signals. The clamp level, the gain and all of the other settings are controlled via a serial interface (either I2C-bus or 3-wire serial bus, selected via a logic input). The IC also includes a PLL that can be locked to the horizontal line frequency and generates the ADC clock.| Part No. | TDA8752B |
