MAX9122EUE+T Applications

The MAX9122EUE+T is a low power, single-channel, differential line driver/receiver that can interface between Open-Drain/Open-Collector (OD/OC) and TTL/CMOS circuits. This high-performance, bidirectional transceiver device is designed for use in single-ended and low-power applications, such as digital LCD panels and diagnostic equipment. The MAX9122EUE+T can also be used in many other applications including data transmission, data acquisition, and touch sensing. Additionally, the MAX9122EUE+T can be used in a variety of voltage level environments, including 1.5V, 2.5V, 3.3V, and 5V.

The MAX9122EUE+T enables bidirectional communication between circuits operating at different voltage levels. This makes it ideally suited to applications where mixed logic levels are used, such as those in modern electronic products. In addition, the MAX9122EUE+T supports wide range of speed and distance requirements with its various features like ac coupling, low frequency operation, single-ended mode and echo cancellation. Last but not least, it has programmable rise and fall times, which makes it suitable for applications having different timing requirements.

MAX9122EUE+T Working Principle

The MAX9122EUE+T consists of a differential line driver and receiver that are connected to each other in a bidirectional manner. When the device is in the transmitting (Tx) mode, the line driver drives data onto the line. The line receiver senses the data and amplifies it to a TTL/CMOS level. Conversely, when the device is in the receiving (Rx) mode, the line receiver receives data from the line and amplifies it to a TTL/CMOS level. The line driver then drives the data back onto the line.

The MAX9122EUE+T supports data transmission rates from DC to 27 Mbps. When in the Tx mode, the line driver has a programmable rise and fall time to reduce signal distortion, reflection and ringing. The MAX9122EUE+T also supports data shaping for reduced signal jitter. The line receiver has a low-pass filter for noise-reduction and an echo-cancellation feature. This echo-cancellation feature enables the MAX9122EUE+T to remain synchronized in asynchronous applications, such as LVDS.

Conclusion

The MAX9122EUE+T is a low power, single-channel, differential line driver/receiver that is ideal for applications requiring mixed voltage levels. It has a programmable rise and fall time and data shaping features, allowing it to meet various speed and distance requirements. Additionally, it has an echo-cancellation feature for synchronizing the device in asynchronous applications. This makes the MAX9122EUE+T an attractive solution for a variety of applications.
