DS560DF810ALUR

Overview

The DS560DF810ALUR is an eight-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, including PAM4 and NRZ modulation types. 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 package with 135 pins.

Feature Summary

• Supports independent CDR locking for multiple baud rate and modulation combinations without host intervention.
• Integrates advanced equalization stages including CTLE, RX FFE, DFE, and adjustable TX FFE for reach extension.
• Includes a full 2x2 crosspoint between adjacent channels for lane switching and multiplexing flexibility.
• Features built-in diagnostic tools such as an eye opening monitor, PRBS generator, and error checker.

Applications

• Active electrical cables (AEC) using QSFP-DD or OSFP form factors
• Front-port C2M attachment unit interface jitter cleaning
• Backplane and midplane C2C attachment unit interface reach extension
• Speed doubling gearbox applications with NRZ-to-PAM4 aggregation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Materials Information to confirm tape and reel quantities. Confirm moisture sensitivity level ratings and peak reflow temperatures prior to assembly. Ensure I2C configuration requirements align with system controller capabilities or external EEPROM availability.

Selection Notes

Select this component when designing systems requiring eight-channel signal regeneration for lossy interconnects. Verify that the application requires the specified 19.6 to 28.9 GBd data rate range. Confirm compatibility with the required PAM4 or NRZ protocols. Evaluate PCB routing constraints against the integrated AC coupling capacitors and 2x2 crosspoint capabilities.
