ICS90C65 VGA Interface
The
ICS90C65
has two system interfaces: System Bus and
VGA Controller, as well as other programmable inputs. Figure
1 shows how the Integrated Circuit Systems’s VGA Clock
ICS90C65
is connected to a VGA controller. Western Digital
Imaging VGA controllers normally have a status bit that indi-
cates to the VGA controller that it is working with a clock chip.
When working with a clock chip the VGA controller changes
two of its clock inputs to outputs. They are
theVCLK1/VCSLD/VCSEL and VCLK2/VCSEL/VCSELH
outputs and they are used to select the required video frequency.

When the power-down capabilities are used, the control signal
for PWRDN is normally held in one of a group of latches. If
the power-down function is not to be used,
PWRDN must be
tied to V
DD
, otherwise the internal pull-down will place the chip
in the power-down mode.
