AD8191A: 4:1 HDMI/DVI Switch with Equalization
Product Description
The AD8191A is an HDMI™/DVI switch featuring equalized TMDS® inputs and pre-emphasized TMDS outputs, ideal for systems with long cable runs. Outputs can be set to a high impedance state to reduce the power dissipation and/or to allow the construction of larger arrays using the wire-OR technique.
The AD8191A is provided in a 100-lead LQFP, Pb-free, surface-mount package specified to operate over the −40°C to +85°C temperature range.
Product Highlights
- Supports data rates up to 1.65 Gbps, enabling 1080p HDMI formats and UXGA (1600 × 1200) DVI resolutions.
- Input cable equalizer enables use of long cables at the input (more than 20 meters of 24 AWG cable at 1080p).
- Auxiliary switch routes a DDC bus and two additional signals for a single-chip, HDMI 1.2a receive-compliant solution.
Applications
- Multiple input displays
- Projectors
- A/V receivers
- Set-top boxes
- Advanced television (HDTV) sets
