DS280BR810ZBFT

The DS280BR810ZBFT from Texas Instruments is a high-performance, octal-channel linear equalizer designed for multi-rate, multi-protocol interfaces up to 28 Gbps. This device is crucial for extending the reach and enhancing the robustness of high-speed serial links in applications such as front-port, backplane, and chip-to-chip communication.

Key electrical specifications include a maximum data rate of 28 Gbps across 8 channels, with typical low power consumption of 93 mW per channel. It features ultra-low latency of 100 ps (typical) and provides channel reach extension of over 15 dB. The device operates from a single 2.5V ±5% power supply.

Designed for ease of integration, the DS280BR810ZBFT comes in a small 8-mm x 13-mm BGA package. It includes integrated RX and TX AC coupling capacitors for simplified flow-through routing. The unique pinout allows high-speed signals to be routed underneath the package, facilitating cleaner board layouts. This redriver operates within a temperature range of -40°C to 85°C and is suitable for surface mount applications.

This component is well-suited for extending signal integrity in demanding communication systems. Its linear equalization supports seamless link training for CR4/KR4 interfaces, and it does not require a heat sink, further simplifying system design.
