GENERAL DESCRIPTION
The AD8192 is a complete HDMI/DVI link switch featuring
equalized TMDS inputs and pre-emphasized TMDS outputs
ideal for systems with long cable runs. The TMDS outputs can
be set to a high impedance state to reduce the power dissipation
and/or allow the construction of larger arrays using the wire-
OR technique. The AD8192 includes bidirectional buffering for
the DDC bus and CEC line, with integrated pull-up resistors for
the CEC line. The AD8192 is available in a space-saving, 56-lead
LFCSP surface-mount, lead-free plastic package specified to
operate over the 40°C to +85°C temperature range.
PRODUCT HIGHLIGHTS
1.
Fully HDMI 1.3a transmit and receive compliant.
2.
Supports data rates up to 2.25 Gbps, enabling greater than
1080p HDMI formats with deep color (12-bit) and UXGA
(1600 × 1200) DVI resolutions.
3.
Input cable equalizer enables use of long cables; more than
20 m (24 AWG) at data rates up to 2.25 Gbps.
4.
Auxiliary switch isolates and buffers the DDC bus and the
CEC line, improving total system capacitance limit.
5.
Hot plug detect (HPD) signal is pulsed low on link switch.
6.
Manually or automatically switched input terminations.
