The TLK2201A and TLK2201AI gigabit ethernet transceivers provide for ultrahigh-speed full-duplex point-to-point

data transmissions. These devices are based on the timing requirements of the 10-bit interface specification by

the IEEE 802.3 Gigabit Ethernet specification. The TLK2201A supports data rates from 1.0 Gbps through 1.6

Gbps and the TLK2201AI supports data rates from 1.2 Gbps through 1.6 Gbps.
