Overview for Redriver/Repeater

Texas Instruments' redriver/repeater portfolio features low power products with multiple channels.


Key portfolio highlights

  • Extend signal reach: Input and output equalization to support 30+ inches of FR-4 or 8+ meters of copper cable @ 10Gbps
  • Lowest power and system cost: Single-supply voltage with <70 mW per channel (typical); no external reference clock, power supply filters or complex routing needed
  • Easy to use: Multi-protocol support and automatic configuration via external EEPROM eliminates need for software programming

Key applications

TI repeaters support various protocols such as:
