AD8134
SYNC-ON-COMMON-MODE
The AD8134 drives RGB video signals over UTP cable. The
balance of the differential outputs is trimmed to ensure low
radiated energy from each of the twisted pairs. The common-
mode outputs of each of the R, G, and B differential outputs
are set using the circuit in Figure 32. This circuit embeds the
horizontal and vertical sync pulses on the three common-mode
outputs in a way that also results in low radiated energy. For a
more detailed description of the sync scheme, see the
Applications section.

On a single 5 V supply, the sync-on-common-mode circuit can
be used by directly applying the H
SYNC
and V
SYNC
signals to the
respective AD8134 inputs. The logic thresholds of the H
SYNC
and
V
SYNC
inputs are nominally set at (V
S+
V
S
)/4, using a resistor
divider with an impedance of approximately 200 kΩ. This
allows the inputs to be driven beyond the rails without logic
inversion and maintains fast switching speeds. The robustness
of the H
SYNC
and V
SYNC
inputs therefore allows them to be driven
directly off the output of a computer video card without concern of
overdriving the inputs. The input path from H
SYNC
and V
SYNC
inputs to the switches in the current mode level-shifting circuit
are well matched to eliminate false switching transients. This
maximizes common-mode balance and minimizes radiated
energy.
The sync-on-common-mode circuit generates a current based
on the SYNC LEVEL input pin (Pin 18). With SYNC LEVEL
input tied to V
S
, the common-mode output of all drivers is set
at (V
S+
+ V
S
)/2. Using a resistor divider, a voltage can be
applied between V
S
and SYNC LEVEL that determines the
maximum deviation of the common-mode outputs from their
midsupply level. If, for instance, SYNC LEVEL V
S
= 0.5 V
and the supply voltage is 5 V, then the common-mode outputs
fall within an envelope of 2.5 V ± 0.5 V. The state of each V
OUT, cm
output based on the H
SYNC
and V
SYNC
inputs is determined by
the equations defined in the Applications section.
The sync-on-common-mode circuit can be used with ±5 V
supplies, but in this case, the H
SYNC
and V
SYNC
logic signals
require level-shifting. Level-shifting details are provided in the
Applications section.
