AD8195:  1:1 HDMI/DVI Buffer with Equalization

Product Description

The AD8195 is an HDMI™/DVI buffer featuring equalized TMDS inputs and preemphasized TMDS outputs, ideal for systems with long cable runs. The AD8195 includes bidirectional buffering for the DDC bus and bidirectional buffering with integrated pull-up resistors for the CEC bus. The DDC and CEC buffers are powered independently of the TMDS buffers so that DDC/CEC functionality can be maintained when the system is powered off.

The AD8195 is specified to operate over the −40°C to +85°C temperature range.

Product Highlights

  1. Enables a fully HDMI 1.3a-compliant front panel input.
  2. Supports data rates up to 2.25 Gbps, enabling 1080p deep color (12-bit color)
    HDMI formats and greater than UXGA (1600 × 1200) DVI resolutions.
  3. Input cable equalizer enables use of long cables; more than 20 meters (24 AWG)
    at data rates up to 2.25 Gbps.
  4. Auxiliary buffer isolates and buffers the DDC bus and CEC line for a single chip,
    fully HDMI 1.3a-compliant solution.
  5. Auxiliary buffer is powered independently from the TMDS link so that DDC/CEC
    functionality can be maintained when the system is powered off.
