ANALOG DEVICES HDMI/DVI Buffer with Equalization AD8195
●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 meets all the requirements for sink tests as defined in Section 8 of the HDMI Compliance Test 1.3c.
The AD8195 is specified to operate over the −40°C to +85°C temperature range.
