maintain temporal fidelity when derived from
composite video. One such case involves
applications in which several video sources are
polled by an instrument which then extracts
photometric data from video. . . |

Video Circuit Clamps under All
Conditions: 4/23/98
EDN-Design Ideas / Many video-circuit Clamps
operate well in the presence of a
composite-video signal but cannot achieve a
Clamp level with signals other than composite
video or in the absence of an input signal. This
circuit, developed for the ADC1175 (a popular
and inexpensive, high-performance, 8-bit,
20M-sample/sec ADC), provides the normal
back-porch Clamp function to the input of the
ADC in the presence of a composite-video signal.
The circuit further ensures that the voltage
presented to the ADC is within its correct
operating range in the absence of an input
signal and forces any signal other than
composite video to be within the ADCs input
common-mode range |

EDN-Design Ideas / Video multiplexers route
video from several sources to a single channel.
Low-end consumer products use CMOS analog
switches and multiplexers, such as the 4066 and
4051. Unfortunately, these devices have a series
on-resistance that ranges from approximately
100Ω to 1 kΩ, a resistance that is not constant
with video level and that appears in series with
the signal.... |
