Overview
The DS280MB810ZBLR, produced by Texas Instruments, is an extremely low-power, high-performance eight-channel linear equalizer designed to support multi-rate, multi-protocol interfaces up to 28 Gbaud NRZ. This component is engineered to extend the reach and improve the robustness of high-speed serial links for various applications, including backplane, front-port, and chip-to-chip connections. It features integrated signal conditioning and a 2x2 cross-point switch between each pair of adjacent channels, enabling 2-to-1 multiplexing, 1-to-2 de-multiplexing, and signal cross-over to aid in PCB routing.
