10/100/1000 Mbps PHY with SerDes and DC/DC Regulator

Topology: Other


The XWAY™ PHY11G family of Physical Layer (PHY) ICs incorporates a set of single Gigabit-Ethernet (GbE) PHY devices that support 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 tandards are exceeded by the XWAY™ PHY11G family. Implementation of an integrated SerDes allows for support of 1000BASE-X and SGMII.The XWAY™ PHY11G family is characterized by an ultra-low power consumption of 400 mW in 1000BASE-T mode. Support of Energy-Effi cient 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, dual-media and media-conversion applications for both copper and fi ber media. In applications using the copper medium, the low-EMI line driver with integrated termination facilitates a simplifi ed PCB design. The PHY devices are available in the VQFN48 and LQFP64 small-package variants, thereby setting a new benchmark in footprint minimization. Both package types support the RMII, RGMII interface types, while the latter additionally supports GMII.Optionally, the devices 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 XWAY™ PHY11G devices are confi gurable via pin-trapping, by means of the MDIO interface, or optionally by connecting an external EEPROM.
