Figure 4. Three Resolution Slew-Rate Control
Figure 4 showcases the setup for three commonly used
resolutions: 1600 x 1200, 1280 x 1024, and 1024 x 768.
Since the resolution change is relatively slow, the
switch does not have to be fast. The impedance of the
switch does not need to be low compared to RRX.
When using a high-impedance switch, the resistance
from the switch should be included to calculate RRX.
The MAX4731 50Ω SPST analog switch shown in the
figure is used with three external resistors to get RRX
values of 10kΩ, 23.5kΩ, and 47kΩ for 1600 x 1200,
1280 x 1024, and 1024 x 768 resolutions, respectively.
