It is a physical layer device that combines many functions, including drivers, receivers, transceivers, and more. The device provides design flexibility, operation reliability, and EMC compliance.

Overview:

The DP83847ALQA56AX/NOPB is a cost-effective, low-power, transceiver plus multiple physical layer functions. It is specifically designed to meet the requirements of high-speed communication systems. The device offers a wide range of features and flexibility in terms of speed and functionality. It includes a built-in equalizer, spread spectrum clocking, a dedicated crystal reference clock, pre-emphasis, and emphasis for enhanced data rates.

Application Field:

The device is used in multiple communications applications such as Ethernet, digital sound systems, broadband access systems, as well as automotive infotainment and connected car applications. It is used in systems that require EMC compliance, as it features high blocking level, low idle channel emissions, and high transmit and receive common mode isolation. In addition, the device can be used in ultra-stable power line interfaces, Active Mode, and Active Standby modes.

Working Principle:

The DP83847ALQA56AX/NOPB functions as a transceiver, and includes drivers, receivers and transceivers, to enable communication with remote devices. It uses a differential transmission scheme with electrically symmetrical (balanced) signaling. The device has an internal line driver and receiver, operating up to 3.125 GB/s data rate. The receiver preamplifier has a programmable equalizer for extended reach capability and offers rejection of high-frequency disturbance signals.

The device uses an internal programmable oscillator circuit to provide an externally adjustable spread spectrum clock, which ensures low EMI. It also includes programmable pre-emphasis and de-emphasis, which optimize frequency response when working at data rates above 1000 Mbps. The device features high-speed registers, SROM and sleep and power down functions, all of which help to minimize power consumption.

Conclusion:

The DP83847ALQA56AX/NOPB is a low-cost and low-power physical layer device that combines a variety of functions, including drivers, receivers, and transceivers. It is used in systems that require liberal electro-magnetic compatibility (EMC), as it features excellent blocking level, low idle channel emissions and pre-emphasis/emphasis for enhanced data rates. It also includes an internal programmable oscillator and pre-emphasis/de-emphasis circuit for minimized power consumption and optimal frequency response when working at data rates above 1000 Mbps.
