RGBHV Driver with EMI Suppression

resistor to the input. This results in an equivalent imped-
ance of 75 at the DAC output, which indicates to the
video controller’s internal load-detection circuit that the
load is disconnected and the video controller shuts down
the video output. Figure 2 and Table 1 demonstrate how
the MAX9511 load-detection circuit operates in conjunc-
tion with the video controller load detection.
Output Video Signal Level Shift
The video signal at the MAX9511 output is shifted
upwards by approximately 240mV from the input to
keep the output stage of the video driver in a linear
region of operation. At the connector, the video signal
is attenuated by 6dB, canceling the 6dB gain of the
video driver. The 240mV level shift is also attenuated by
6dB, and hence the actual video signal seen by the
load is only 120mV higher than the video signal at the
input of the MAX9511. Monitors and other display
devices AC-couple the input signal so the 120mV level
shift should not affect the displayed video image.
