Lan8720ai-cp-tr qfn-24 Ethernet IC has the lowest price
explain
Lan8720a / lan8720ai is a low-power 10Base-T / 100base-tx physical layer (PHY) transceiver with variable I / O voltage, which complies with IEEE802 3-2005 standard. Lan8720a / lan8720ai supports communication with Ethernet MAC through standard RMII interface. It includes a full duplex 10-base-T / 100base-tx transceiver and supports 10Mbps (10Base-T) and 100Mbps (100base-tx) operations. Lan8720a / lan8720ai realize automatic negotiation to automatically determine the best possible speed and duplex operation mode. Hpauto mdix support allows the use of direct or cross LAN cables.
Lan8720a / lan8720ai supports both IEEE802 3-2005 compatible function, and also supports vendor specific register function. However, the operation does not require register access. The initial configuration can be selected through the configuration pin described in section 3.7 "configuration strap" on page 29. Register selectable configuration options can be used to further define the function of the transceiver.
According to IEEE802 3-2005 standard, all digital interface pins can tolerate 3.6V. The device can be configured to operate on a single 3.3V power supply using an integrated 3.3V to 1.2V linear regulator. The linear regulator can be optionally disabled, allowing the use of efficient external regulators to reduce system power consumption. Lan8720a / lan8720ai have extended commercial and industrial temperature range versions.
