DS280DF810ABWR

The DS280DF810ABWR from Texas Instruments is an octal-channel multi-rate retimer featuring integrated signal conditioning. It is engineered to extend the reach and enhance the robustness of long, lossy, high-speed serial links, achieving a bit error rate of 10-15 or less.

Each of the eight channels independently locks to serial data rates ranging from 20.2Gbps to 28.4Gbps, including sub-rates like 10.1376Gbps, 10.3125Gbps, and 12.5Gbps. This retimer boasts ultra-low latency, typically less than 500 ps for a 28.4Gbps data rate. It incorporates advanced equalization features, including an adaptive continuous-time linear equalizer (CTLE), an adaptive decision feedback equalizer (DFE), and a low-jitter 3-tap finite impulse response (FIR) filter.

The DS280DF810ABWR supports combined equalization for channel loss up to 35+dB at 12.9GHz and 30+dB at 14GHz. It operates from a single power supply and includes integrated AC coupling capacitors, reducing board routing complexity and Bill of Materials (BOM) cost. The device features an adjustable transmit amplitude from 205mVppd to 1225mVppd and includes on-chip eye opening monitor (EOM) and PRBS pattern checker/generator capabilities.

This retimer is housed in a compact 8.00mm x 13.00mm BGA package, designed for easy flow-through routing. Its unique pinout allows high-speed signals to be routed underneath the package. The operating temperature range is extended from -40°C to 85°C, making it suitable for demanding applications. It is ideal for backplane and mid-plane reach extension, jitter cleaning for front-port optics, and electrical interfaces such as IEEE802.3bj 100GbE, Infiniband EDR, and OIF-CEI-25G-LR/MR/SR/VSR.
