The MC92604 Dual Gigabit Ethernet transceiver (GEt) is a 1.25 gigabaud , full-duplex, data 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 MC92604 is designed with the intent to fully support full-duplex Ethernet 1000BASE-X applications as specified in IEEE Std. 802.3-2002.

The MC92604 is two parts in one. It may be configured as a dual 1 gigabit GMII or TBI PHY for Ethernet 1000BASE-X applications or it is a dual 1 gigabit backplane serializer/deserializer, SerDes. The dual MC92604 may optionallt be configured as a single channel transceiver with serial link redundancy. The device fully supports the MDIO interface defined in the above referenced standard.

The GEt 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 Dual 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 MC92604 is offered in a JEDEC standard 196 pin 15 mm square body size package to provide excellent board density in applications with a large number of channels.
