PEF7071支持半双工和全双工这两种模式下的10BASE-T(e)，100base-TX，1000base-T标准，并超过了这些标准所设置的性能。集成了SerDes从而可支持1000BASE-X和SGMII接口。

  在1000BASE-T模式下，PEF7071具有低功耗400 mW的特点。支持节能以太网标准依据链路利用率可进一步降低功耗。网络唤醒功能的使用引入了系统级的电能节省。其综合设计集成了对铜和光纤媒体的单媒体和媒体转换应用的支持。在使用铜介质的应用中，集成了低EMI线路驱动器的终端可简化PCB设计。这个PHY器件采用PG-VQFN-48小型封装型号，在封装面积最小化方面树立了新的基准。PEF 7071器件支持RGMII和SGMII接口类型。

   PEF7071器件可通过使用集成式DC / DC开关稳压器以2.5 V至3.3 V的单电源供电，达到最小的外部成本。PEF7071器件可通过引脚绑定，MDIO接口或连接外部EEPROM来进行配置。

The PEF7071 supports the 10BASE-T(e), 100BASE-TX, 1000BASE-T and 1000BASE-X standards in both the half-duplex and full-duplex modes. The performance requirements set by these standards are exceeded by the PEF7071. Implementation of an integrated SerDes allows for support of 1000BASE-X and SGMII.

   The PEF7071 is characterized by an low  power  consumption of 400 mW in 1000BASE-T mode. Support of Energy Ecient Ethernet allows for an even further reduction in power consumption that depends on link utilization. Power savings at system level are introduced using the Wake-on-LAN feature. The comprehensive design of the ICs integrates support for single-media and media-conversion applications for both copper and fiber media. In applications using the copper medium, the low-EMI line driver with integrated termination facilitates a simplified PCB design. The PHY devices are available in the PG-VQFN-48 small-package variants, thereby setting a new benchmark in footprint minimization. PEF 7071 device supports the RGMII and SGMII interface types.

   Optionally, the PEF7071 device can be operated from a single power supply, with a range of 2.5 V to 3.3 V by using the integrated DC/DC switching regulator with minimal external cost. The PEF7071 device is configurable via pin-strapping, by means of the MDIO interface, or optionally by connecting an external EEPROM.
