Description

The TDA8752 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 of the TDA8752 also includes a PLL that can be locked on the horizontal line frequency and generates the ADC clock. The PLL jitter is minimized for high resolution PC graphics applications. An external clock can also be input to the ADC.

It is possible to set the TDA8752 serial bus address between four fixed values, in the event that several TDA8752 ICs are used in a system, using the I2C-bus interface (for example, two ICs used in an odd/even configuration).
