DS8923AN Application Field and Working Principle

The DS8923AN is an integrated line transceiver, receiver and driver that ideal for balanced and differential line applications. It is designed to provide voltage amplification between two complementary voltages or currents and is used in data communications for driving and receiving. The DS8923AN is especially suited for applications requiring high performance, extreme temperature range and low power consumption. The transceiver is designed to provide low jitter and low distortion in both transmitted and received signals.

Application Field

The DS8923AN is commonly found in applications including Ethernet, Fibre Channel and other fiber optic based systems, memory boards, video interfaces, and backplane applications. It can also be found in console ports, input/output modules, and storage area networks. Furthermore, the transceiver can be found in applications aiming to improve bus performance, reduce costs, and optimize the power consumption.

Working Principle

The DS8923AN line transceiver integrates three main blocks: the receiver, the driver and the transceiver. The receiver is responsible for amplifying the weak incoming signals, and the driver is used to further strengthen the signals. The transceiver is responsible for high-level buffering of input signals from the receiver and output signals from the driver. The transceiver is also responsible for isolating the receiver and driver from the external environment for enhanced performance.

The transceiver allows the input signals to be transformed into differential signals, which provide better noise reduction than single-ended signals. During the transformation, the input differential signals are amplified and combined before being presented to the receiver. The transceiver amplifies the input signals through a differential gain stage, and then provides a controlled impedance to improve the signal-to-noise ratio. The driver is then responsible for further amplifying the input signals and prepares them for transmission.

The DS8923AN line transceiver can achieve data transfer rates up to 1Gbps, and is optimized for both low-speed and high-speed applications. The receiver is designed to operate both single- and double- ended inputs, and is configurable for either single-ended or differential AC or DC clocked outputs. The transceiver features a programmable output edge steering logic, which helps minimize the skew between inputs and outputs. The driver also provides various output levels, which can go as low as -18dB. Furthermore, the transceiver features a quad serial-data-input structure, which allows for up to four data ports with independent programming.

Conclusion

The DS8923AN line transceiver is an ideal solution for boosting signal transmission and reduce noise in applications such as Ethernet, Fibre Channel, memory boards, video interfaces, and backplane applications. It is capable of achieving data transfer rates up to 1Gbps, and provides programmable output edge steering logic, programmable levels of output, and a quad serial-data-input structure. Furthermore, the transceiver is designed to operate in extreme temperature ranges, and has low power consumption.
