BLACK BURST GENERATION FOR DAC CROSSTALK TEST
In the three-channel video DACs, the signal of one channel may leak to others so that some part of it may be
detected at the other channel outputs. Such interference is called crosstalk. In order to measure them, the SDO
provides a special test mode – Black burst test mode. In this mode, one selected DAC channel generates normal
CVBS signal and the remaining two channels do black burst signal. The black burst signal is the same as CVBS
but does not contain any active video information. By doing that, the measured any non-black signal during active
video of black burst channel is the amount of crosstalk.
