GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD8194 is a low cost quad 2:1 TMDS® switch for high

speed HDMI™/DVI video applications. The AD8194 features

equalized inputs, ideal for systems with long cable runs. Its

primary function is to switch the high speed signals from one

of two single-link (HDMI or DVI) sources to the single-link

output. The AD8194 is a fully buffered switch solution with 50 Ω

input and output terminations, providing full-swing output

signal recovery and minimizing reflections for improved system

signal integrity.

1. Data supports rates up to 2.25 Gbps, enabling greater than

1080p deep color (12-bit color) HDMI formats and greater

than UXGA (1600 × 2300) DVI resolutions.

2. Fully buffered inputs and outputs.

3. Input cable equalizer enables use of long cables at the

input. For a typical 24 AWG cable, the AD8194 compen-

sates for more than 20 m at data rates up to 2.25 Gbps.

4. Matched 50 Ω on-chip input and output terminations

improve system signal integrity.

5. Single-pin source select bit.

6. Low added jitter.

The AD8194 is provided in a space-saving, 32-lead, LFCSP,

surface-mount, RoHS-compliant, plastic package and is specified

to operate over the −40°C to +85°C temperature range.
