1. General description

2. Features

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 other settings are controlled via a serial interface

(either I

The IC also includes a PLL that can be locked to 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 TDA8752B serial bus address to four different values, when

several TDA8752B ICs are used in a system, by means of the I

example, two ICs used in an odd/even conﬁguration).
