Analog Devices Inc. EVAL-CN0422-EBZ Circuit Evaluation Board

Analog Devices Inc. EVAL-CN0422-EBZ Circuit Evaluation Board offers galvanic isolation of the HDMI 1.3a protocol using iCoupler^® isolation technology. iCoupler technology isolates the low voltage differential signaling (LVDS) physical layer at data rates in excess of 1Gbps, reducing complexity in systems where both isolation and high bandwidth are required.

The EVAL-CN0422-EBZ Circuit provides a completely isolated connection between a High-Definition Multimedia Interface (HMDI) source and an HDMI sink device. Isolation in this circuit increases system safety and robustness by providing protection against electrical line surges. The isolation also breaks the ground connection between the bus and digital pins, thereby removing possible ground loops within the system.

The EVAL-CN0422-EBZ Circuit Evaluation Board enables start-up communication sequence through the ADN4654, ADuM1250, and ADuM5020 devices between the HDMI source and HDMI sink. The board also incorporates the ADP7104 LDO and the ADP5302 step-down regulator.
