The TLK2218 is the third generation of Gigabit Ethernet transceivers from Texas Instruments combining high port density and ultra-low power in a small form-factor footprint. The TLK2218 provides for high-speed full-duplex point-to-point data transmissions based on the IEEE 802.3z 1000-Mbps Ethernet specification. The TLK2218 supports data rates from 1.0 Gbps through 1.3 Gbps in full rate mode, or 0.5 Gbps through 0.65 GbPs in half rate mode.
