The GPY111 is an ultra-low power, multi-mode Gigabit Ethernet (GbE) PHY IC, supporting speeds of 10, 100 and 1000 Mbit/s in full-duplex or half-duplex mode. It can be used in various data flows based on twisted-pair and fiberoptic communication links. The main application is the copper mode, where Media-Independent Interface (MII) data is converted to a Media-Dependent Interface (MDI) based on the 10BASE-T(e), 100BASE-TX and 1000BASE-T Ethernet standards.
The GPY111 supports a number of features for convenience and reliability, including auto-negotiation, auto-MDIX, auto-downspeed and cable wiring fault correction. In addition, the integrated cable diagnostics mode, the test packet generator, and the various test loops can be used for analysis and debugging of the target system. The GPY111 includes an integrated serializer/deserializer (SerDes) that can be used to operate a fiber link in conjunction with a 1000BASE-X fiber module. This capability enables media converter data flow applications.
