Some Tips on the Most Effective Programming of
the EL4544
The video inputs present a 1.75k
Ω single ended and a 3.5kΩ
differential load to an incoming video signal. Since this load
is in parallel with the external termination network, it has a
consistent effect on the system gain. To maintain this
consistency, it is inadvisable to program more than one input
stage (Ai, Bi, Ci, or Di) to "look" at any given video input
(RGB0, RGB1, …, RGBF) since each activated input stage
puts an additional parallel load of 3.5k
Ω onto the selected
input. When programming the serial interface this is simply
expressed as: Avoid programming the same value into the
four data registers (for Ai, Bi, Ci, and Di) at hex addresses
0H, 1H, 2H, and 3H. They should all have unique values.
This is important since if any inputs are selected more than
once, their gains will mismatch an input that has only been
selected once.
If one wishes to broadcast the same signal to multiple output
channels, this can easily be accomplished without violating
the advice of the previous paragraph. Select the input that
needs to be broadcast using any one of the four input
selectors (Ai, Bi, Ci, or Di), then have any of up to five of the
output stages (Ax, Bx, Cx, Dx, Sx) point to the input stage
that is pointing to the desired input signal. These are
selected using hex 8H, 9H, AH, BH, and CH. Now the
EL4544 is broadcasting a single video source to multiple
outputs without excessively loading down the selected input.
Sync Decoding of EL4544
The EL4544 is designed to receive and decode Horizontal
and Vertical Sync signals that have been encoded as
common-mode signals of the Red, Green, and Blue Video
inputs. The EL4543 provides this encoding as shown in
Table 1.
The EL4544 decodes the common-mode signals into H and
V syncs as follows: Horizontal Sync is TRUE when the
Blue_Common_Mode voltage is greater than the
Average_of_Red_and_Green_Common_Mode voltage.
Vertical Sync is TRUE when the
Average_of_Red_and_Blue_Common_Mode voltage is
greater than the Green_Common_Mode voltage. The sync
comparators have an internal symmetrical hysteresis that is
less than ±50mV. Timing skews between comparators under
all conditions are less than one pixel. The comparators have
an input common mode that allows for operation at least 1V
from the negative supplies and at least 1.5V from the
positive supplies.
