78Q8392LA03-28CHR/F

The 78Q8392LA03-28CHR/F is a digital quad differential line driver, receiver and transceiver used in various industries as a peripheral device. In its most common application, the device is used to interface with digital signals over shared bus architectures. The interface includes two channels for transmitting and two for receiving, allowing for the control of four independent data signals.

Applications

The 78Q8392LA03-28CHR/F is commonly used in communications, automation and industrial control systems where multiple data signals need to be driven and/or received. Additionally, it can be used in data acquisition and test equipment, laser printers, RAID arrays and other applications that require the transmission or reception of four-channel digital signals.

Within communications applications, the device is suitable for use as a line driver for differential pairs in RS-485, RS-422 and CAN bus systems. It is also used in applications that require the simultaneous transmission of four independent control signals, such as TDM (time division multiplexing) systems, multiplexed clocks, differential pulse-width modulation (PWM) and pulse position modulation (PPM) systems. Its ability to drive up to four independent signals makes it ideal for use as an interface in advanced embedded devices.

The 78Q8392LA03-28CHR/F is popular in the automotive industry, where it is used as a peripheral device in advanced devices such as in-vehicle networking systems and engine controllers. This eliminates the need for multiple discrete components and reduces the overall size of the system.

Working Principle

The 78Q8392LA03-28CHR/F is a fully differential line driver, receiver, and transceiver. It is designed to interface with digital input/output (I/O) signals, allowing for high speed data transmission over shared network architectures. The interface consists of two transmitting channels (T1 and T2) and two receiving channels (R1 and R2). Each channel can be driven or received independently, enabling up to four independent data signals to be transmitted and/or received.

The device features ESD (electrostatic discharge) protection, high common-mode noise immunity, high speed 8Mbps operation, and is capable of driving up to 76mA over a differential of 0.4V·μs. It also has a low-power standby mode, allowing the device to enter a low-power state when it is not actively transmitting or receiving data.

The 78Q8392LA03-28CHR/F uses differential signaling, which is a method of transmitting two separate signals simultaneously on the same line. This technique provides superior noise and immunity compared to single-ended signal transmission. By using differential signaling, the device can ensure reliable transmission of data in both high-noise and low-noise environments.

The device also features an enhanced power-on reset circuit, which ensures that the device functions properly when power is applied. This eliminates the need for external reset circuitry, enabling easy integration into existing systems.

Conclusion

The 78Q8392LA03-28CHR/F is a digital quad differential line driver, receiver, and transceiver, used in various industries as a peripheral device.
