Texas Instruments DS110DF111
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, cross-talk-impaired high speed serial links to achieve BER < 1x10-15.| Part No. | DS110DF111 |

DESCRIPTION
For lessdemanding applications and interconnects, the DFE can be switched off and achieve the same BER performance. The DS125DF111 and DS110DF111 devices are pin-compatible. Each channel of the DS110DF111 independently locks to serial data at data rates from 8.5 to 11.3 Gbps or to any supported subrate of these data rates.
