Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The YT8522A is a low-power, single-port 10/100 Mbps Ethernet PHY. The YT8522 provides all the physical layer functionality required to send and receive data over a standard twisted pair transceiver or fibre optic PECL interface to an external 100Base-FX optical transceiver module. In addition, the YT8522 provides flexible connectivity to MACs via standard MII and RMII interfaces.

The YT8522 uses mixed-signal processing to perform equalisation, data recovery and error correction for robust operation over CAT5 twisted pair or 100Base-FX fibre optic transceivers.
