MAX14972CTG+

Signal Buffers, Repeaters, Splitters Overview

The MAX14972CTG+ is a dual SuperSpeed USB 3.0 equalizer and redriver manufactured by Analog Devices Inc./Maxim Integrated. It utilizes programmable input equalization and output deemphasis to mitigate deterministic jitter and restore signal integrity degraded by circuit-board or cable losses. The device operates on a single +3.3V supply and features advanced power management with receiver detection, supporting USB 3.0 low-frequency periodic signals (LFPS). Packaged in a compact 24-pin TQFN (4.0mm x 4.0mm) with flow-through traces for optimal layout, it is specified for the commercial operating temperature range of 0°C to +70°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides high-level integration through programmable three-level input equalization and six-level output deemphasis to compensate for signal loss.
• Features advanced power management capabilities including explicit LFPS support and multiple low-power states such as standby and dynamic power-down.
• Ensures signal integrity with very low latency, characterized by a typical propagation delay of 250ps and excellent jitter compensation.

Signal Buffers, Repeaters, Splitters Applications

• Restoring signal integrity in SuperSpeed USB 3.0 interconnects affected by trace or cable losses
• Enabling optimal placement of key components by allowing longer circuit-board traces
• Space-sensitive applications requiring minimal footprint via small TQFN packaging

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix CTG against official documentation to confirm package type and temperature rating. Ensure compatibility with single +3.3V supply requirements. Confirm RoHS3 compliance status through current manufacturer declarations. Validate that the commercial temperature range meets system operational needs.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing SuperSpeed USB 3.0 links requiring active signal restoration. Consider its low latency and integrated termination for high-speed performance. Evaluate power consumption across active, standby, and detect states against system efficiency targets. Verify pinout compatibility with existing layout constraints due to the specific TQFN form factor.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the MAX14978 family of USB switch ICs and related interface solutions from Maxim Integrated. It specifically addresses signal conditioning for USB 3.0 standards rather than simple switching. The device complements other Maxim interface products by providing active equalization where passive components are insufficient for maintaining signal quality over extended distances.
