Retimers

TI's retimers provide signal integrity solutions that extend signal reach, while resetting the system jitter budget. With multiple channels this broad portfolio of delivers a variety of channel configurations for scalable front port and backplane solutions.


Key portfolio highlights

  • Extend reach, eliminate jitter: Fully-adaptive input and output equalization to support 30+ inches of FR-4 or 8+ meters of copper cable @ 10Gbps; integrated clock and data recovery circuit (CDR) resets jitter budget
  • Low power, low system cost: Single-supply voltage with <150 mW per channel (typical) @ 12.5Gbps; no external reference clock for VCO tuning, power supply filters, or complex routing needed
  • Easy to use: Wide operating frequency range and automatic configuration via external EEPROM eliminates need for software programming; built-in eye monitoring and test pattern generation

Key applications

  • Backplane: PC board reach extension and jitter cleaning
  • Front port: reach extension, jitter cleaning and spec compliance (ex. SFF-8431/8436), active copper cable assembly

TI retimers support various protocols such as:
