Texas Instruments DS280BR810 28Gbps 8-Ch Linear Repeater
Texas Instruments DS280BR810 28Gbps 8-Channel Linear Repeater is an extremely low-power, eight-channel linear equalizer. It supports multi-rate, multi-protocol interfaces up to 28Gbps. This device is used to extend the reach and improve the robustness of high-speed serial links for front-port, backplane, and chip-to-chip applications. The linear nature of the DS280BR810's equalization preserves the transmit signal characteristics. This allows the host and link partner ASICs to freely negotiate transmit equalizer coefficients. Transparency to the link training protocol facilitates system-level interoperability with minimal effect on the latency. Each channel operates independently, which allows the DS280BR810 to support individual lane Forward Error Correction (FEC) pass-through.
