General Description

The DS125RT410 is a four-channel retimer with integrated signal conditioning.

The device includes a fully adaptive continuous-time linear equalizer (CTLE), clock and data recovery (CDR), and a transmit de-emphasis (DE) driver to enable data transmission over long, lossy and crosstalk-impaired highspeed serial links to achieve BER < 1 × 10–15.

For channels with a high amount of crosstalk, the DS125DF410 should be used because it has self calibrating 5-tap decision-feedback equalize
