2 Device Overview

The Texas Instruments PCIe Gen5.0 redrivers amplify high frequency content of incoming signals affected by ISI (Inter-Symbol-Interference). This amplification is done while adding minimal RMS jitter. PCIe Gen5.0 redrivers are designed for Gen4.0 and lower rates as well. Furthermore, these devices are protocol agnostic and can be used for CXL, SAS, and other applications.

Please see each device-specific data sheet referenced in Section 7 for details regarding internal block diagram, receiver equalization, linearity, and register programming.
