3 Description

The DS125BR401 device is an extremely low-power

high-performance multiprotocol repeater and 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 continuous time linear

equalizer (CTLE) of the receiver provides a boost of

up to 30 dB at 6.25 GHz (12.5 Gbps) in each of its eight channels and can open an input eye that is

completely closed due to intersymbol interference

(ISI) induced by interconnect medium such as

backplane traces of 30 inches or more or copper

cables of 8 meters or more, 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.
