DS125DF111: What is the difference between retimer and redriver

Hi David,

Redrivers use equalization and gain adjustment to compensate for insertion loss and re-transmit an equalized signal.
Retimers use the same techniques to equalize an attenuated signal, while also using a CDR circuit to filter jitter out of the same signal.

Redrivers and retimers can both compensate for insertion loss, while only retimers are designed to compensate for random jitter.

Thank you,

Evan
