TDA8757A
Triple 8-bit ADC 205 Msps
Rev. 01 — 22 March 2002
Preliminary data
1.
General description
The TDA8757A is a triple 8-bit ADC for the digitizing of large bandwidth RGB/YUV
signals at a sampling rate up to 205 Msps.
The IC supports display resolutions up to 1600
× 1200 (UXGA) at 75 Hz.
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 signal can also be used to clock the ADC.
The outputs are available either on one port up to 110 Msps or on two ports up to
205 Msps. The operating mode is selectable with the serial interface for either
I2C-bus or 3-wire serial bus (3W-bus) operation.
The clamp level, the gain and the other settings are controllable through the serial
interface.
