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.
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.
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...
