DS110DF111 - Texas Instruments

DS110DF111 2-Channel Retimer

The DS110DF111 is a dual-channel (1-lane bidirectional) retimer with integrated signal conditioning. The DS110DF111 includes an input Continuous-Time Linear Equalizer (CTLE), clock and data recovery (CDR), and transmit driver on each channel. The DS110DF111 with its on-chip Decision Feedback Equalizer (DFE) can enhance the reach and robustness of long, lossy.
