Overview
SFP điện 10-100-1000BASE-T Copper SFP Transceiver
The electrical Small Form Factor Pluggable (SFP) transceiver module is specifically designed for the high performance integrated full duplex data link at 1.25Gbps over four pair Category 5 UTP. The transceiver module is compliant with the SFP MultiSource Agreement (MSA) and IEEE802.3:2002. With the hot pluggability, the module offers a flexible and easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipments operating online. The 1000BASE-T electrical SFP transceivers use an integrated RJ-45 connector with transformer and PHY IC. The link length is up to 100m over four pair Category 5 UTP cabling

Block Diagram
The transceiver is fundamentally consisted by three parts: RJ45+Magnetics, PHY IC and EEPROM. The transceiver module can be turned on by setting TX_DISABLE = LOW and can be reset by setting TX_DISABLE = High or OPEN. TX_FAULT is not supported in Copper products
and always be connected to ground. For accessing the serial identification information, an EEPORM is used to store the required data via the 2-wire serial CMOS EEPROM protocol. The detailed signal descriptions are listed in the following sections. The registers of PHY IC are also
accessible via the 2-wire serial CMOS EEPROM protocol at address ACh.
