Product Summary
The TLK1221RHA is a gigabit Ethernet transceiver. It provides for high-speed full-duplex point-to-point data transmissions. The TLK1221RHA is based on the timing requirements of the 10-bit interface specification by the IEEE 802.3 Gigabit Ethernet specification. The TLK1221RHA supports data rates from 0.6 Gbps through 1.3 Gbps. The primary application of these devices is to provide building blocks for point-to-point baseband data transmission over controlled-impedance media of 50Ω. The transmission media can be printed-circuit board traces, copper cables or fiber-optical media. The ultimate rate and distance of data transfer is dependent upon
