●Product Details
●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.
●Product Highlights
● 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.
