ICS1532
110 MHZ TRIPLE 8-BIT ADC WITH CLOCK GENERATOR
Chapter 9 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.
