It is designed for use in Motor Control, Automobiles and Industrial Automation applications. The device is suitable for operation over the full temperature range and has a wide operating supply voltage range.

Application Field

The LTC2863HDD2#PBF is ideally suited for bidirectional communication and data exchange between multiple nodes across a long distance. It can be used to interface two devices in a reflective clock environment, transmit and receive data over a differential line. This device also supports a wide range of data protocol formats such as I2T, SPI, UART, CAN, etc.

The LTC2863HDD2#PBF is a low-power, high- efficiency device with small line capacitance and low electromagnetic interference (EMI). It is designed to support data rates up to 1Mbps and offers reduced crosstalk and excellent common mode noise rejection. It is also suitable for multiplexed data bus systems.

The device supports a wide input voltage range from 3V to 5.5V and is designed for industrial and automotive applications with a temperature range of -40°C to +125°C.

Working Principle

The LTC2863HDD2#PBF uses a differential transmitter and receiver architecture. The differential signal pins (D*+ and D*-) of the device are the input and output pins respectively, while the differential driver power pins (VDD, GND) act as common mode voltage references.

The transmitter circuit uses a differential amplifier to transmit data in the form of a differential signal. The output of the differential amplifier is coupled to the differential pair D*+ and D*- and the amplified differential signal is transmitted over the output line. The receiver circuit uses an equalizer circuit with a selectable gain which amplifies the differential signal and then transmits it to the receiver to obtain the data.

The LTC2863HDD2#PBF offers a number of features such as programmable input thresholds and output drivers, automatic data flow control, built-in level shifters, adjustable transmitter pre-emphasis and adjustable receiver equalizers.

The device is fully compatible with the Pulse Width Modulation (PWM) modulation, Manchester and RS-485 communication protocols. It also supports fault signaling between nodes for error-free communication.

The LTC2863HDD2#PBF also supports integrated auto-power up, keep-alive and sleep modes which ensure optimal power consumption, reliable communications and system stability.

The device is also designed for a wide range of applications including motor control, automotive and industrial automation systems. It is a highly integrated and cost effective solution for implementing wide area bus communications in automotive and industrial automation applications.
