DS125BR401 4-Lane PCI Repeater

Texas Instruments' DS125BR401 is an extremely-low-power, high-performance, multi-protocol repeater/redriver designed to support four lanes of PCIe Gen-3/2/1, 10G-KR, 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 30 in+ backplane traces or 8 m+ copper cables, hence enabling host controllers to ensure an error-free end-to-end link. The transmitter provides a de-emphasis boost of up to -12 dB and output voltage amplitude control from 700 mV to 1300 mV to allow maximum flexibility in the physical placement within the interconnect channel.
