GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

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.
