DS560DF810ALUT

Signal Buffers, Repeaters, Splitters Overview

The DS560DF810ALUT is an eight-channel multi-rate retimer with integrated signal conditioning. It supports PAM4 and NRZ data rates from 19.6 to 28.9 GBd, including div-by-2 and div-by-4 sub-rates. The device features a continuously adaptive CTLE, RX FFE, DFE, and a programmable 4-tap TX FFE filter to support channel losses exceeding 30 dB at 13.28 GHz. An integrated 2x2 crosspoint enables flexible lane switching. It operates on dual 1.8-V and 1.2-V supplies within a -40°C to +85°C temperature range. The component is housed in an 8.00 mm × 13.00 mm FCCSP (ALU) package containing integrated AC coupling capacitors.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports automatic lane rate switching for CDR lock across multiple baud rates and modulation types without host intervention.
• Includes gearbox mode functionality for NRZ-to-PAM4 bit mux/demux and serializer/deserializer operations.
• Provides diagnostic capabilities via an on-chip eye opening monitor, PRBS generator, and error checker.

Signal Buffers, Repeaters, Splitters Applications

• Active electrical cables (AEC) utilizing QSFP-DD or OSFP form factors
• Front-port C2M attachment unit interface jitter cleaning
• Backplane and midplane C2C attachment unit interface reach extension

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ALUT against the current Texas Instruments Package Option Addendum to confirm the 250-unit carrier quantity and SNAGCU lead finish. Ensure that the selected variant matches the required moisture sensitivity level and peak reflow temperature specifications for the intended manufacturing process.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring independent channel locking for both PAM4 and NRZ protocols up to 28.9 GBd. The integrated 2x2 crosspoint and gearbox modes are essential for applications demanding lane aggregation, de-aggregation, or failover redundancy without external multiplexing hardware.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS560DF810 family of high-speed serial link solutions. It serves as a critical signal integrity component for extending the reach of lossy interconnects such as direct-attach copper cables and backplanes. The device replaces discrete equalization and retiming circuits by consolidating these functions into a single BGA package.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Consult the official TI orderable addendum for verified substitute part numbers within the same product family. Do not assume functional equivalence with other retimers lacking integrated crosspoints or gearbox capabilities.

Signal Buffers, Repeaters, Splitters FAQ

Does the DS560DF810 require external AC coupling capacitors?

No, the device includes integrated physical AC coupling capacitors for both transmit and receive paths, eliminating the need for external components on the PCB.

What is the maximum supported symbol rate for this retimer?

Each channel independently locks to symbol rates in a continuous range from 19.6 to 28.9 GBd for both PAM4 and NRZ formats.
