AD8192
Rev. 0 | Page 21 of 28
CABLE LENGTHS AND EQUALIZATION
The AD8192 offers two levels of programmable equalization
for the high speed inputs: 6 dB and 12 dB. The equalizer of
the AD8192 supports video data rates of up to 2.25 Gbps and
can equalize more than 20 meters of 24 AWG HDMI cable at
2.25 Gbps, which corresponds to the video format 1080p with
12-bit deep color. The length of cable that can be used in a
typical HDMI/DVI application depends on a large number
of factors including
Cable quality: the quality of the cable in terms of conductor
wire gauge and shielding. Thicker conductors have lower
signal degradation per unit length.
Data rate: the data rate being sent over the cable. The signal
degradation of HDMI cables increases with data rate.
Edge rates: the edge rates of the source input. Slower input
edges result in more significant data eye closure at the end
of a cable.
Receiver sensitivity: the sensitivity of the terminating
receiver.
As such, specific cable types and lengths are not recommended
for use with a particular equalizer setting. In nearly all applica-
tions, the AD8192 equalization level can be set to high, or 12 dB,
for all input cable configurations at all data rates, without degrading
the signal integrity.
TMDS OUTPUT RISE/FALL TIMES
The TMDS outputs of the AD8192 are designed for optimal
performance even when external components are connected
such as external ESD protection, common-mode filters, and
the HDMI connector. In applications where the output of the
AD8192 is connected to an HDMI output connector, additional
ESD protection is recommended. The capacitance of the additional
ESD protection circuits for the TMDS outputs should be as low
as possible. In a typical application, the output rise/fall times are
compliant with the HDMI 1.3a specification at the output of the
HDMI connector.
FRONT PANEL BUFFER FOR ADVANCED TV
A front panel input provides easy access to an HDMI connector
for connecting an HD camcorder or video game console to an
HDTV. In designs where the main PCB is not near the side or
front of the HDTV, a front panel buffer must be connected to
the main board by a cable. The AD8192 enables the implemen-
tation of a front or side panel HDMI input for an HDTV by
buffering the HDMI signals and compensating for the cable
interconnect to the main board.

HDMI SWITCHER
In home theatre applications where more HDMI inputs are
needed, a multiple input HDMI switcher can be used to extend
the number of available HDMI inputs. This switch can be con-
tained within an audio/video receiver (AVR) or as a standalone
unit. The AD8192 can be cascaded to create larger arrays as
shown in Figure 32.

CASCADING MULTIPLE DEVICES
Unlike traditional I2C bidirectional buffers, the DDC/CEC
buffers in the AD8192 can be cascaded to create larger arrays
such as those shown in Figure 32. The TMDS signals can also
be cascaded, although it is important to use caution because
cascading high gain equalizers can increase the output jitter
beyond acceptable limits. In such cases, set the programmable
equalizer in the AD8192 to low (6 dB).
