Figure 20(A). Muxed Ramp at 1000 Ms/s with Blanking
Multiplexed behavior is shown in Figure 20A and 20B,
with a counter input muxed against fixed levels at
1000 Ms/s and at 1350 Ms/s, respectively.
In Figure 20A, the ramp is muxed against a steady
state mid-scale value, while in Figure 20B, the steady
state input is 11111111. The apparent droop in the top
level in Figure 20B is an artifact of the sampler.
Figures 19A, 19B, and 20A show the effects of blanking,
while in Figure 20B, the BLANK input is held LOW,
demonstrating the repetitive nature of the waveform.
Note: In Figure 20(A), A0–A7 are switched, B0–B6 are LOW,
B7is HIGH and BLANK is switched. In Figure 20(B),
A0–A7 are switched, B0–B7 are HIGH, and BLANK is LOW.

Blanking Disabled
