DS10BR254TSQ

Overview

The DS10BR254TSQ is a high-performance, low-power 2.5 Gbps to 6.25 Gbps retimer designed for serial data transmission applications. It features two independent channels with integrated CDR (Clock and Data Recovery) circuits to regenerate signals over lossy interconnects. The device supports various encoding schemes including 8b/10b and 64b/66b. It operates from a single 3.3V supply and includes programmable equalization settings to optimize signal integrity across different channel lengths and materials. The TSQ suffix indicates an automotive-grade qualification compliant with AEC-Q100 standards, ensuring reliability in demanding vehicular environments.

Feature Summary

• Dual-channel architecture with independent clock and data recovery for each lane
• Supports data rates from 2.5 Gbps up to 6.25 Gbps
• Automotive-grade qualification for enhanced reliability in vehicle systems
• Integrated programmable equalization to compensate for channel loss

Applications

• Automotive infotainment and display interfaces
• In-vehicle networking links requiring signal regeneration
• High-speed serial communication backplanes in automotive modules

Procurement Notes

Verify the specific revision level and packaging type when ordering. Confirm that the automotive grade designation aligns with your project's reliability requirements. Check for any recent updates to the datasheet regarding pin compatibility or recommended operating conditions. Ensure that the supplier provides traceability documentation if required by your quality management system.

Selection Notes

Consider the DS10BR254TSQ when designing systems that require robust signal integrity over long copper traces or PCB channels in automotive applications. Evaluate the power consumption against thermal constraints within the enclosure. Compare the input/output voltage levels with other components in the signal chain to ensure compatibility. Assess the need for external equalization components based on the specific channel loss characteristics of your design.

Part Context

This component belongs to the DS10BR series of retimers, which are widely used in high-speed serial data applications. The 'TSQ' suffix specifically denotes an automotive-grade variant, distinguishing it from commercial or industrial versions. These devices are critical for maintaining signal quality in modern electronic systems where data rates exceed the capabilities of passive interconnects.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as other DS10BR variants with different speed grades or package options. Verify functional equivalence regarding data rate support and power supply requirements before substituting.
