DS560DF410AMNT

Overview

The DS560DF410AMNT is a quad-channel multi-rate retimer with integrated signal conditioning, designed for high-speed serial links. It supports symbol rates from 19.6 to 28.9 GBd in both PAM4 and NRZ formats, including sub-rates. The device features continuously adaptive CTLE, RX FFE, DFE, and an adjustable 4-tap TX FFE filter to support channel losses exceeding 30 dB at 13.28 GHz. It includes an integrated 2x2 crosspoint, on-chip eye opening monitor, PRBS generator/checker, and physical AC coupling capacitors. Power supplies are dual 1.8-V and 1.2-V. Operating temperature ranges from -40°C to +85°C. It is housed in a 7.65 mm × 7.65 mm FCCSP-81 package.

Feature Summary

• Quad-channel multi-protocol retimer supporting independent CDR lock for PAM4 and NRZ data rates
• Advanced equalization with adaptive CTLE, RX FFE, DFE, and programmable 4-tap TX FFE
• Integrated 2x2 crosspoint enabling lane switching, multiplexing, and fanout capabilities
• Built-in diagnostic tools including EOM, PRBS generator/checker, and temperature sensor

Applications

• Active electrical cables (AEC) such as SFP, SFP-DD, QSFP, QSFP-DD, and OSFP
• Front-port C2M attachment unit interface (AUI) jitter cleaning
• Backplane (KR) and midplane C2C AUI reach extension
• Speed doubling gearbox applications with NRZ-to-PAM4 aggregation and de-aggregation

Procurement Notes

Verify the specific ordering suffix 'AMNT' against the manufacturer's current orderable addendum to confirm the small tape-and-reel quantity of 250 units. Ensure compatibility with the FCCSP-81 package dimensions and moisture sensitivity level requirements during storage and handling prior to soldering.

Selection Notes

Select this component when designing systems requiring flexible lane management via the integrated 2x2 crosspoint or when utilizing gearbox modes for protocol conversion between NRZ and PAM4. Confirm that the host system can accommodate the dual voltage supply requirements and I2C or EEPROM configuration methods.

Part Context

This part belongs to the DS560DF410 series of multi-rate retimers. It serves as a signal conditioning solution for extending the reach of lossy interconnects like DAC cables and backplanes. The AMN package variant integrates AC coupling capacitors, reducing external component count compared to non-integrated variants.

Replacement Considerations

Consult the TI orderable addendum for alternative package options within the same family, such as the AMNR variant which offers a larger tape-and-reel quantity.
