It operates up to 5-V supply voltage and provides medical-grade thin-film ceramic packages with ESD protection up to 15-kV HBM. The PI6ULS5V9515AWE serial bus transceiver provides full-duplex buffering of one differential data line. The net-to-node data-bit rate is up to 400 Mbps at 5 V.

Application Field

PI6ULS5V9515AWE can be applied in a variety of embedded system applications, such as in automotive infotainment systems, automotive HMI, industrial Ethernet networks, PROFIBUS-DP/PA networks, and industrial automation systems. In addition, the PI6ULS5V9515AWE offers CAN FD (CAN with flexible data rate) support that helps to improve system signal integrity during automotive data-bus transmission.

Working Principle

The PI6ULS5V9515AWE serial bus transceiver is designed to serve as an interface between two different logic families. It enables data communication between two nodes (transmitters) by using differential voltage levels. The logic 1 input is represented by a higher voltage level compared to the logic 0 input. The high-frequency signal shape is preserved by the differential outputs with the help of an internal output loop connection. The PI6ULS5V9515AWE supports a symmetric output level of up to 1200 mV. The PI6ULS5V9515AWE offers ±15-kV HBM ESD protection and 40-V IEC61000-4-2 ESD contact protection for A port, B port, and VC (for Power Earphone) pins.

The PI6ULS5V9515AWE transceiver is connected in-between two nodes (transmitters) through differential voltage lines. The transceiver accepts one differential signal from one node and transmits a differential signal to the other node. The signal is buffered by the transceiver before it is passed to the other node. By doing so, the noise generated by the signal is filtered out and the signal integrity is improved.

The PI6ULS5V9515AWE transceiver is designed to provide data rates up to 400 Mbps at 5 V and allows for maximum signal amplitude of 1500 mV. It also contains programmable output impedances and drive strength, making it suitable for a variety of applications. It is also capable of supporting both high-speed (up to 4 Mbps) and low-speed (up to 400 kb/s) communication, allowing the user to configure it according to the needs of the application.

The PI6ULS5V9515AWE transceiver has an AC-coupled receiver input. This input helps to reduce reflections from the interconnect between the nodes, thus improving signal integrity. It also reduces the amount of jitter introduced in the signal, leading to higher data rate precision.

The PI6ULS5V9515AWE also contains slew rate control logic, which limits the slew rate of the outputs in order to reduce the amount of switching noise. Additionally, the transceiver features a programmable bit-width control, which helps to reduce the propagation delay. This enables the user to reduce the latency of the data transmission and improve the communication speed.

In conclusion, the PI6ULS5V9515AWE transceiver provides full-duplex buffering and is suitable for communication interface applications such as automotive infotainment systems and industrial Ethernet networks. It can operate up to 5-V supply voltage and supports data rates up to 400 Mbps at 5 V. The transceiver offers improved signal integrity, reduced jitter and increased data rate precision. These features make it an ideal choice for embedded systems applications that require high data rate, low latency and low power consumption.
