DS100KR401 Datasheet 4-Lane Repeater

Manufacturer: Texas Instruments

Overview: DS100KR401 www.ti.com SNLS395B – JANUARY 2012 – REVISED MARCH 2012 DS100KR401 Ultra Low Power, 4 Lane (8-channel, bi-directional) Repeater for Data-rates up to 10.

General Description

The DS100KR401 is an extremely low power, high performance repeater designed to support 4 lane (bidirectional) 10G-KR and other high speed interface serial protocols up to 10.3 Gbps.

The receiver's continuous time linear equalizer (CTLE) provides a boost of up to +36 dB at 5 GHz (10.3125 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 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 dB and output voltage amplitude control from 700 mV to 1300 mV to allow maximum flexibility in the physical placement within the interconnect channel.
