Input Termination

The ICS1532 is a high speed Analog to Digital

converter capable of operating at 110 MSPS. Since

VGA/VESA video is comprised of 700 mV vpp

waveforms potentially toggling high speed, care needs

to be taken to preserve the quality of these analog input

signals from reflections and coupled noise all the way

to the input pins of the ICS1532.

The R, G and B video inputs and their dedicated return

signals must be…

• Routed as a clean, minimal length traces to

minimize loading and pickup

• 75 Ohm characteristic impedance to

eliminate reflections

• Appropriate signal pairs being located as

close as possible to each other and far from

noise sources

• Properly terminated as shown in Figure 9-1

with termination resistors placed as close to

the ICS1532 as possible.
