DS280DF810ABWR

Signal Buffers, Repeaters, Splitters Overview

The DS280DF810ABWR is an eight-channel multi-rate retimer supporting data rates from 20.2Gbps to 28.4Gbps, including sub-rates like 10.1376Gbps and 12.5Gbps. It operates on a single 2.5V power supply with integrated AC coupling capacitors (220nF) and 100Ω input termination. The device features adaptive CTLE, adaptive DFE, and a 3-Tap FIR filter for up to 35dB channel loss compensation at 12.9GHz. Transmit amplitude ranges from 205mVppd to 1225mVppd. It utilizes a 135-pin fcBGA package measuring 13mm by 8mm and supports operation between -40°C and 85°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ABWR suffix against the manufacturer's current orderable information to confirm package type and availability. Ensure system design accommodates the required 2.5V power supply and SMBus interface pull-up requirements. Confirm that the operating temperature range meets the application environment specifications before finalizing procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when high-density eight-channel retiming is required for links exceeding 20Gbps. The integrated AC coupling reduces bill of materials cost and board routing complexity compared to discrete solutions. Verify that the target interconnect loss characteristics fall within the specified equalization capabilities of the adaptive CTLE and DFE blocks.
