The SN75LVDS389DBTR is a tiny discrete differential line driver and receiver designed to achieve data rates up to 3Mbps in a typical application. The device is suitable for use in applications such as digital audio, video, and other high-speed digital data transmission applications. The SN75LVDS389DBTR is a low voltage differential signal (LVDS) transceiver.

An LVDS transceiver transfers signals between an electrical source, such as a microcontroller, and an external device, such as a display panel, over a differential line. The differential line provides more reliable data transmission than the common single-ended signal for digital data. The SN75LVDS389DBTR is part of the TI LVDS Ultra-Broadband family, which provides high-performance signal transmission over ultra-short cable runs.

Application Field of SN75LVDS389DBTR

The SN75LVDS389DBTR is designed to interface LVDS-based data sources within an extremely small array package. Its use cases include, but are not limited to, digital video applications, automotive infotainment systems, Industrial & Automation, telecom and data communications systems, multi-touch systems, and embedded system interfaces.

The device offers low power consumption and high data rate, making it ideal for applications that require high-speed digital data transfer but with low power consumption. The extremely small package size of the device also makes it useful for space-constrained applications.

Working Principle of SN75LVDS389DBTR

The SN75LVDS389DBTR consists of a single-ended driver and a differential receiver. The driver side transmits data over a differential line, while the receiver side is responsible for sensing the incoming differential signal and converting it into a single-ended signal. The receiver usually consists of a differential amplifier and a comparator.

The driver amplifies the input signal and feeds it to the differential line. The input signal is then detected by the receiver and compared to a reference voltage by the comparator. The output of the comparator is the single-ended output signal.

The SN75LVDS389DBTR is designed with a 0.7V supply, making it suitable for applications with low power requirements. It also features a low idle-mode power consumption, making it even more reliable in low power scenarios. The device also offers a sleep mode that keeps the power consumption at an even lower level.

Conclusion

In conclusion, the SN75LVDS389DBTR is an LVDS transceiver suitable for use in a wide variety of digital and data communication applications where space is limited and power consumption is a concern. Its driver and receiver are capable of transferring data at rates up to 3Mbps, while its low idle-mode power consumption ensures that power is not wasted.
