The GPY112 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 GPY112 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 GPY112 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 data flow applications like media converters and dual-media flows with media auto-detection, as well as simple MII-to-fiber modes.
The MII pins of the GPY112 can be re-assigned to form one of several standard MII interfaces such as MII, RMII, GMII, RGMII and SGMII. In RGMII mode, the integrated delay function for the TX and RX clock simplifies PCB design. In SGMII mode, the PHY does not require a receive clock and instead uses the integrated Clock and Data Recovery (CDR).
