DS560MB410ZAST

Signal Buffers, Repeaters, Splitters Overview

The DS560MB410ZAST is a low-power, four-channel linear redriver manufactured by Texas Instruments. It supports multi-rate interfaces up to 28 GBd using PAM4 modulation and 32 GBd using NRZ modulation. The device operates on a single 2.5-V ± 5% power supply with typical channel power consumption of 160 mW. It features selectable CTLE boost profiles for PCB or cable loss compensation and an integrated 2x2 crosspoint for signal routing. The component utilizes an nFBGA-101 package measuring 6.00 mm × 6.00 mm and functions within an ambient temperature range of -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Quad-channel linear equalizer supporting multi-rate protocols including Ethernet, Fibre Channel, and InfiniBand
• Integrated 2x2 crosspoint with pin or register control for multiplexing, fanout, and signal crossing
• Selectable CTLE boost profiles optimized for either PCB or copper cable loss compensation
• Ultra-low additive jitter and input-to-output latency of 80 ps (typical)

Signal Buffers, Repeaters, Splitters Applications

• Backplane (KR) and midplane C2C attachment unit interface (AUI) reach extension
• Active copper cables (ACC) such as SFP56, QSFP56, QSFP-DD, or OSFP
• Multiplexer and de-multiplexer configurations for failover redundancy

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZAST corresponds to the small tape-and-reel carrier configuration containing 250 units per reel. Confirm that the SNAGCU lead finish meets system solderability requirements. Ensure SMBus pull-up resistors are implemented externally in the design, as the device requires them for controller or target mode operation.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending high-speed serial links beyond standard ASIC capabilities without requiring heat sinks. The device is suitable for applications demanding transparent link training and FEC pass-through. Verify that the required data rate does not exceed 28 GBd for PAM4 or 32 GBd for NRZ signals before finalizing the design.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS560MB410 family of linear redrivers designed for high-speed data center interconnects. The ZAST suffix specifically denotes the small tape-and-reel packaging option, distinguishing it from the large tape-and-reel variant (ZASR). Both variants share identical electrical characteristics and pinouts.

Signal Buffers, Repeaters, Splitters Replacement Considerations

DS560MB410ZASR serves as the primary alternative offering identical functionality in a large tape-and-reel format.
