Next, a 15m DualLink DVI cable was attached and
terminated into a female TPA2 adapter and the eye captured
in Figure 4.
The eye is not meeting the minimum requirements of either
the HDMI or DVI standards and the Dell Monitor is unable to
recover the data and display an image.
Setup B inserts an ISL54105 and an additional 15m cable
between the pattern generator and the monitor:
Given the input signal shown in Figure 4, the ISL54105’s
TMDS output signal (Figure 6) is extremely clean. The
output is an improvement over the original signal coming
from the pattern generator in both amplitude and jitter.
The cleaner signal generated at the output of the ISL54105
results in an improved eye at the end of another 15m cable
(Figure 7). The eye is open enough that the Dell 2000FP can
now display a UXGA image with no visible sparkle or other
artifacts.
Tx Loading Considerations
When the ISL54105 is powered-up and its Tx outputs are
disabled, via either the PD (power-down) pin, the
power-down register bit (register 0x02[5]), or the tri-state
outputs bits (register 0x05[1:0]), the Tx pins are high
impedance. In this state, they will draw no current from the
Rx pins of any TMDS receiver they may be connected to.
However, if power to the ISL54105 is removed, the Tx pins
are no longer high-impedance. Figure 8 shows the relevant
equivalent circuit, including the internal ESD protection
diodes. For simplicity, only one of the eight Tx outputs, ESD
protection diodes, and Rx termination resistors are shown.
When VD to the ISL54105 drops below ~2.7V and power is
applied to the external TMDS receiver, ESD protection
diodes inside the ISL54105 can become forward-biased,
