Document Table of Contents Receiver Buffer

The receiver input buffer receives serial data from input pin and feeds the serial data to the clock data recovery (CDR) unit and deserializer.

The receiver buffer supports the following features:

  • Programmable differential On-Chip Termination (OCT)
  • Signal Detector
  • Continuous Time Linear Equalization (CTLE)
  • Variable Gain Amplifiers (VGA)
  • Adaptive Parametric Tuning Engine
  • Decision Feedback Equalization (DFE)
  • On-Die-Instrumentation (ODI)
Note: ODI is fully supported for H-Tile devices. However, for L-Tile devices, ODI is a functional diagnostic utility for remote system debug and link tuning, in other words, up to 25.8 Gbps. The ODI feature does not support relative channel-to-channel comparisons on L-Tile devices.
