Overview
The TLK2711AJRZQE, produced by Texas Instruments, is a high-speed transceiver belonging to the WizardLink family of multigigabit transceivers. It is designed for ultrahigh-speed bidirectional point-to-point data transmission systems, supporting serial interface speeds from 1.6 Gbps to 2.7 Gbps. This device is particularly useful for applications requiring high-speed I/O data channels over controlled impedance media such as printed-circuit boards, copper cables, or fiber-optic cables. The TLK2711AJRZQE offers significant power and cost savings over traditional parallel data transmission architectures by reducing the number of traces, connector terminals, and transmit/receive terminals.
