The receiver's continuous time linear equalizer (CTLE) provides a boost of up to +36 d B at 5 GHz (10.3125 Gbps) in each of its eight channels and is capable of opening an input eye that is pletely closed due to inter symbol interference (ISI) induced by interconnect medium such as long backplanes or cables, hence enabling host controllers to ensure an error free endto-end link. The transmitter provides a de-emphasis boost of up to -12 d B and output voltage amplitude control from 700 m V to 1300 m V to allow maximum flexibility in the physical placement within the interconnect channel. When operating in 10G-KR mode, the DS100KR401 transparently allows the host controller and the...
