Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability
DescriptionThe MAX9179 is a quad low-voltage differential signaling (LVDS) line receiver designed for applications requiring high data rates, low power dissipation, and noise immunity. The receiver accepts four LVDS input signals and translates them to 3.3V LVCMOS output levels at speeds up to 400Mbps. The receiver MAX9179 features built-in hysteresis, which improves noise immunity and prevents multiple switching on slow transitioning inputs.
The MAX9179 supports a wide 0.038V to 2.362V commonmode input voltage range, allowing for ground potential differences and common-mode noise between the driver and the receiver. A fail-safe circuit sets the output high when the input is open, undriven and shorted, or undriven and terminated. Common enable inputs of MAX9179 control the highimpedance outputs.
The MAX9179 has a flow-through pinout for easy PC board layout, and is pin compatible with the MAX9121 and the DS90LV048A with the additional features of high ESD tolerance and built-in hysteresis.
The MAX9179 operates from a single 3.3V supply, and is specified for operation from -40°C to +85°C. The device is offered in 16-pin TSSOP and thin QFN packages.
