The DS125DF111 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 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 performance. The DS125DF111 and DS110DF111 devices are pin-compatible.
Each channel of the DS125DF111 independently locks to specific serial data at data rates from 9.8 to 12.5 Gbps or to any supported sub-rate of these data rates. This simplifies system design and lowers overall cost.
Programmable transmit de-emphasis driver offers precise settings to meet the SFF-8431 output eye template. The fully adaptive receive equalization (CTLE and DFE) enables longer distance transmission in lossy copper interconnect and backplanes with multiple connectors. The CDR function is ideal for use in front port parallel optical module applications to reset the jitter budget and retime high speed serial data.
