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 * 4 inputs, one output HDMI/DVI link * Pin-to-pin compatible with the AD8197A * 4 TMDS channels per link Supports 250 Mbps to 1.65 Gbps data rates Supports 25 MHz to 165 MHz pixel clocks Equalized inputs for operation with long HDMI cables (20 meters at 1080p) Fully buffered unidirectional inputs/outputs * Globally switchable, 50 Ω on-chip terminations Pre-emphasized outputs Low added jitter Single-supply operation (3.3 V) * 4 auxiliary channels per link Bidirectional unbuffered inputs/outputs Flexible supply operation (3.3 V to 5 V) HDCP standard compatible Allows switching of DDC bus and 2 additional signals
