DS125BR800A datasheet



The DS125BR800A is an extremely low-power high-performance multi-protocol repeater/redriver designed to support eight channels of PCIe, SAS, and other high-speed interface serial protocols up to 12.5 Gbps.

The receiver’s continuous time linear equalizer (CTLE) provides a boost of up to +30 dB at 6.25 GHz (12.5 Gbps) in each of its eight channels and is capable of opening an input eye that is completely closed due to inter symbol interference (ISI) induced by interconnect medium such as 30in+ backplane traces or 8m+ copper cables, hence enabling host controllers to ensure an error free end-to-end link.
