Pericom offers PCI Express (PCIe) ReDrivers at three speed levels and has a ‘family’ for each speed: PCIe GEN1 is 2.5Gb/s (Gigabits per second), PCIe GEN2 is 5.0 Gb/s and PCIe GEN3 is 8.0 Gb/s. It is recommended that if the designer thinks the system will upgrade to a faster speed in the future, then use the higher speed ReDriver. They are all fully ‘backwards’ compatible to the lower speed. All Pericom ReDrivers are rated across the full Industrial Temp Range (-40°C to+85°C).
