Output Enable Control
The ENABLE pin is an LVTTL input that allows the user
to shut off the output-collector currents, thereby reduc-
ing power consumption of the device. Forcing this pin
high turns the output currents off; forcing this pin low
(normal operation) turns the currents on.
Figure 5 shows a simplified circuit for both the output
and enable controls.
Applications Information
Figure 6a shows a typical TMDS channel from a graph-
ics board of a laptop computer to a remote display.
Maintaining a 100
Ω differential impedance for this
channel has its challenges. Besides proper board lay-
out of traces, there are multiple reflection points (A to
H). For example, at interface F in Figure 6a, a circular
arrow shows a reflection at the connector of a remote
display. When these reflections hit another interface,
they reflect again and thus become echoes corrupting
the incident signal. In Figure 6b, the MAX3814 is used
to equalize losses, isolate reflections, and redrive the
transmission line with high fidelity.
