Overview
The TLK2711IRCPG4, produced by Texas Instruments, is a member of the WizardLink transceiver family of multigigabit transceivers. It is designed for use in ultrahigh-speed bidirectional point-to-point data transmission systems. This device supports serial interface speeds ranging from 1.6 Gbps to 2.7 Gbps, providing up to 2.16 Gbps of data bandwidth. The TLK2711IRCPG4 is particularly useful for high-speed I/O data channels over controlled impedance media such as printed-circuit boards, copper cables, or fiber-optic cables.
