FUNCTIONAL OVERVIEW
The TLK2226 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 TLK2226 provides for high-speed
full-duplex point-to-point data transmissions based on the IEEE802.3z 1000Mbps Ethernet specification. The
TLK2226 supports data rates from 1.0 Gbps through 1.3 Gbps. Each channel is capable of operating at 125
Mbps for IEEE Ethernet 100FX mode, and the rate for each channel may be set through MDIO or automatically
sensed and set by the TLK2226.The primary application of this device is to provide building blocks for
developing point-to-point baseband data transmission over controlled impedance media of 50 Ω. 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 the attenuation characteristics of the media and the noise
coupling to the environment.
This device performs the data encoding, decoding, serialization, deserialization, clock extraction and clock
tolerance compensation functions for a physical layer interface device. Each channel operates at up to 1.3 Gbps
providing up to 7.5 Gbps of aggregate data bandwidth over a copper or optical media interface.
