TDA8757
Triple 8-bit ADC 170 Msps
Rev. 07 — 28 February 2002
Preliminary data
1.
General description
The TDA8757 is a triple 8-bit ADC for the digitizing of large bandwidth RGB/YUV
signals at a sampling rate up to 170 Msps.
The IC supports display resolutions up to 1600
×
1200 (UXGA) at 60 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
170 Msps. The operating mode is selectable with the serial interface to for either
I
2
C-bus or 3-wire serial bus (3W-bus) operation.
The clamp level, the gain and the other settings are controllable through the serial
interface.
