Application Information
Video Input Interface
TW2804 has a built-in 2:1 input MUX for software controllable input selections. This MUX can
be used to select two composite video sources. For a typical application, a video input
requires an analog low-pass filter for alias reduction. An illustration is shown in the following
application schematic.
Clamping / AGC
TW2804 has built-in clamping and AGC circuitry. The analog inputs must be AC coupled
through an external 2.2uF capacitor. Without it, no extra external component is needed for
this operation. The clamping and AGC tracking time constant can be controlled through
register setting.
Video Output Interface
All video data and sync outputs of four channels are synchronous to pin CLK27O. Therefore,
pin CLK27O should be connected to four channel interfaces for synchronizing data.
Power-Up
After power-up, TW2804 registers have unknown values. The RSTB pin must be asserted
and released to bring all registers to its default values. After reset, TW2804 data outputs are
tri-stated. The OE (0x3B) register should be written after reset to enable outputs desired.
