DESCRIPTION

The TLK1211RCP gigabit ethernet transceiver provides for ultrahigh-speed, full-duplex, point-to-point data

transmissions. This device is based on the timing requirements of the 10-bit interface specification by the IEEE

802.3 gigabit ethernet specification and is also compliant with the ANSI X3.230-1994 (FC-PH) fibre channel

standard. The device supports data rates from 0.6 Gbps to 1.3 Gbps.
