DS560DF410AMNR

Overview

The DS560DF410AMNR is a quad-channel multi-rate retimer with integrated signal conditioning, designed for high-speed serial links. It supports PAM4 and NRZ data rates from 19.6 to 28.9 GBd, including sub-rates. The device features continuously adaptive CTLE, RX FFE, DFE, and an adjustable 4-tap TX FFE filter to support over 30 dB channel loss at 13.28 GHz. It includes an integrated 2x2 crosspoint, gearbox mode for NRZ/PAM4 conversion, and on-chip diagnostic tools like EOM and PRBS generators. Powered by dual 1.8-V and 1.2-V supplies, it operates within a -40°C to +85°C range and is housed in a 7.65 mm × 7.65 mm FCCSP-81 package.

Feature Summary

• Quad-channel multi-protocol retimer with independent CDR locking for PAM4 and NRZ signals
• Advanced equalization including adaptive CTLE, RX FFE, DFE, and programmable TX FFE
• Integrated 2x2 crosspoint enabling lane switching, multiplexing, and fanout capabilities
• Built-in gearbox mode supporting NRZ-to-PAM4 aggregation and de-aggregation

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 applications using NRZ-to-PAM4 aggregation and de-aggregation

Procurement Notes

Verify the specific ordering suffix AMNR against the manufacturer's current orderable addendum to confirm production status and packaging quantity. Ensure compatibility with the required moisture sensitivity level and peak reflow temperature specifications during assembly. Cross-reference the part marking code DS560DF4E0 for identification purposes.

Selection Notes

Select this component when designing systems requiring flexible lane switching or gearbox functionality between NRZ and PAM4 protocols. The integrated AC coupling capacitors reduce bill of materials complexity compared to external solutions. Consider the 7.65 mm × 7.65 mm package dimensions for PCB layout constraints and thermal management requirements.

Part Context

This retimer belongs to the DS560DF series, which provides signal conditioning for high-speed interconnects. The AMNR suffix indicates a large tape and reel packaging format with a standard pack quantity of 2000 units. It shares core architectural features with other variants in the family but differs in packaging and shipping configuration.

Replacement Considerations

Direct substitutes include the DS560DF410AMNT, which offers identical electrical performance but utilizes a small tape and reel packaging format with a pack quantity of 250 units. Verify that the change in carrier type does not impact existing automated assembly equipment settings.
