The MC92603 Quad Gigabit Ethernet transceiver (GEt) is a 1.25 gigabaud , full-duplex, interface device that can be used to transmit data between chips across a board, through a backplane, or through cabling, as well as to interface to GBIC/SFP modules. The MC92603 is designed with the intent to fully support full-duplex Ethernet 1000BASE-X applications as specified in IEEE Std. 802.3-2002.

The MC92603 is two parts in one. It may be configured as either a quad 1 gigabit GMII or TBI PHY for Ethernet 1000Base-X applications or it is a 1 gigabit backplane serializer/deserializer, SerDes, similar to the MC92600 Quad SerDes. The quad MC92603 may optionally be configured as a dual channel transceiver with serial link redundancy. The device fully supports the MDIO interface defined in the above referenced standard.

The MC92603 features transmit FIFOs and source-synchronous transmit clocks per channel to further simplify interfacing that will support many other non-Ethernet applications. And finally, IEEE Std. 1149.1 JTAG boundary scan is added for board test support.

The Gigabit Ethernet transceiver is carefully designed for low power consumption and is built upon the proven transceiver technology in the MC92600 and MC92602 Quad SerDes devices. The MC92603 transceiver is offered in a JEDEC standard 256 pin 17mm body size package to provide excellent board density in applications with a large number of channels.
