2 Device Overview

The DS320PR810, DS320PR1601, and other PCIe Gen5 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 redrivers are designed for Gen4 and lower rates as well. Furthermore, these devices are protocol agnostic and can be used for SAS and other applications.
