bottom of the board. Components are mounted both on the
top and bottom sides. The silkscreen (top and bottom) and
all four layers are shown on the following pages. Note the
following special artwork features used to optimize perform-
ance:
- A continuous ground plane is provided underneath all high
speed traces avoiding impedance discontinuities and en-
suring maximum signal integrity
- Copper on the power and ground planes has been re-
movedfromtheareasurroundingthecenterpinoftheoutput
BNC connectors and from underneath the output compo-
nents of the GS9028 cable driver. The purpose of these
cutouts is to reduce the effect of the capacitance added by
the connector and the pads of the components.
-ThegroundplaneassociatedwiththeinputBNCconnector
and input components is isolated from the main board
ground. The purpose of this is to provide a differential input
signal to the equalizer.
APPLICATIONS
The EB9024 evaluation board is designed to show the
characteristics of the GS9024 Equalizer and the GS9028
Cable Driver. This board can also be used as a stand alone
non-reclocking distribution amplifier for serial digital video
signals.
