Introduction

PI4GTL2034LE is an ultra-low-power CMOS octal simultaneous-switching transceiver family with integrated termination resistors. It is pin-compatible with the popular low-voltage differential signaling (LVDS) standard and also supports frequency ranges of up to 1.25 Gb/s as well as long-reach links. It has been designed for applications such as high-speed serial transmission protocols in the automotive, industrial and medical markets, where low-voltage I/O, low power consumption, and high bandwidth are needed. In this article, we will look at the application field and working principle of the PI4GTL2034LE.

Application Field

The PI4GTL2034LE is an ideal solution for automotive or medical applications because of its low-voltage I/O and low power consumption. It is especially suitable for providing LVDS interfaces between systems in automotive and medical applications, as it can provide good data transmission while maintaining low power consumption. Furthermore, the PI4GTL2034LE is qualified according to the Automotive Electronics Council\'s AEC-Q100 specification, making it suitable for use in automotive applications. Additionally, the PI4GTL2034LE can be used for interfacing between high-speed buses and field programmable gate arrays. It is also suitable for applications in telecommunication, industrial and test and measurement systems.

Working Principle

The PI4GTL2034LE employs differential signaling method to transmit data from one device to another. It uses a dual-data-rate signal protocol, which means that the data is transmitted on both wires in both directions. The signal transmission is low-voltage differential signaling (LVDS), which is a balanced signal method that allows for low-noise signal transmission over long cables. The PI4GTL2034LE comprises both voltage-level translators (VLTs) and series termination resistors on both ends of the LVDS line. The VLTs are responsible for translating the signal logic levels to the LVDS levels. The series termination resistors are integrated on both ends of the LVDS line, so that the signal is terminated correctly, ensuring proper signal transmission. The integrated termination resistors also help to reduce system power consumption, as they dissipate less power compared to off-chip termination resistors.

Conclusion

The PI4GTL2034LE is an ultra-low-power CMOS octal simultaneous-switching transceiver family with integrated termination resistors, designed for applications where low-voltage I/O, low power consumption, and high bandwidth are needed. It can be used for LVDS interfaces between systems in automotive and medical applications, as well as for interfacing between high-speed buses and field programmable gate arrays. The signal is transmitted using LVDS, which is a balanced signal method that allows for low-noise signal transmission over long cables, and is terminated using integrated termination resistors.
