AD8192 2:1 HDMI/DVI Switch with Equalization and DDC/CEC Buffers
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.
Fully HDMI 1.3a transmit and receive compliant.
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.
Input cable equalizer enables use of long cables; more than 20 m (24 AWG) at data rates up to 2.25 Gbps.
Auxiliary switch isolates and buffers the DDC bus and the CEC line, improving total system capacitance limit.
Hot plug detect (HPD) signal is pulsed low on link switch.
Manually or automatically switched input terminations.
Front panel buffer for advanced television (HDTV) sets
Standalone HDMI switcher
Multiple input displays
Projectors
A/V receivers
Set-top boxes
