Texas Instruments DS125DF111 Low Power Multi-Rate 2-Channel Retimer

Texas Instruments DS125DF111 Low Power Multi-Rate 2-Channel Retimer is a dual-channel (1-lane bidirectional) retimer with integrated signal conditioning. The DS125DF111 includes an input Continuous-Time Linear Equalizer (CTLE), clock and data recovery (CDR), and transmit driver on each channel. The DS125DF111 with its on-chip Decision Feedback Equalizer (DFE) can enhance the reach and OD: 600 to 1300 mVp-p robustness of long, lossy, cross-talk-impaired high-speed serial links to achieve BER < 1x10-15. For less demanding applications/interconnects, the DFE can be switched off and achieve the same BER Legacy Support performance. The DS125DF111 and DS110DF111 devices are pin-compatible. Each channel of the DS125DF111 independently locks to specific serial data at data rates within the primary range of 9.8 to 12.5 Gbps or to any supported sub-rate of these data rates. Supported data rates can be selected via SMBus using a preprogrammed table or customized as required. This simplifies system design and lowers overall costs.
