1 / 2 page ![]() The MC92604 Dual Gigabit Ethernet transceiver is a 1.25 giga-baud, 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. It was designed with the intent to meet the requirements of IEEE Std. 802.3-2002®. The MC92604 is two parts in one. It may be configured as either a dual channel 1 gigabit backplane serializer/deserializer, SerDes, or it is a dual 1 gigabit GMII or TBI PHY for Ethernet 1000Base-X applications. The dual MC92604 may optionally 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 MC92604 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 MC92604 transceiver is offered in a JEDEC standard 196 pin 15 mm body size package to provide excellent board density in applications with a large number of channels.
