The MAX9371EKA+ is a device used to translate between the low-voltage, single-ended I/Os used in FPGAs, DSPs, and other digital systems, and multi-conductor, differential I/Os used in high-speed applications. This device is known as a logic-translator, level-shifter, and I/O translator—all terms that succinctly describe its function. It performs voltage-level conversion between two system domains (high-voltage differential pairs and low-voltage single-ended signals), thus providing the functionality of a level-shifter, a translator, and an I/O translator.

The MAX9371EKA+ is composed of six output channels, each driving an individually selectable, full-speed or half-speed differential signal. The logic levels have been designed to tolerate a wide voltage range and the outputs are designed to be compliant to the LVDS (Low Voltage Differential Signaling) standard. This logic level is suitable for any high-speed I/O interface such as the PCI Express bus.

The MAX9371EKA+ works by providing a drive voltage for differential data signals ranging from 0V to 7V. The signals are translated from the low voltage domain to the high voltage domain in such a way that there is a linearly increasing relationship between the input and output voltages. Furthermore, the device provides differential outputs which have the same Slew Rate of between 0V and 7V in both directions, meaning that the output rise and fall times remain constant regardless of the voltage applied to the input side. This feature helps to ensure that the system is operating within the maximum speed limits of the LVDS standard.

The MAX9371EKA+ has various other features that make it suitable for high-speed applications. It has an adjustable output swing that allows for the adjustment of the differential drive voltage to ensure the optimum amplitude for the specific system application. Additionally, the device offers a wide range of control options such as a Programmable On-delay circuit and programmable Output Duty Cycle control.

The MAX9371EKA+ offers a high level of integration and flexibility for the designer. It is composed of six identical output stages, with each stage capable of driving a variety of different output signals. The device can be configured to drive either Unidirectional (single data) or Bidirectional (duplexed data) signals. In addition, the device contains internal logic that performs the translation between the low-voltage single-ended input levels and the high-voltage differential levels.

The device utilizes a three-phase protocol, with each phase controlling one of the six output channels. The input and output signals are synchronized, and each phase contains an Enable input and Output Select signals. The Enable inputs and Output Select signals are used to control the data flow between the input and output stages. This helps to reduce power consumption and improve the overall system performance. The device contains internal logic that continually checks the output signals to ensure correct operation.

The MAX9371EKA+ is an ideal logic translator, level shifter, and I/O translator for high-speed applications. The device supports up to six channels, with each channel able to drive a variety of different signals. The device provides easy configuration, a wide range of control options, and a high level of integration for the designer. It is ideal for a variety of different applications, including serial interfaces, storage interfaces, and industrial automation.
