Overview
The DS110DF111SQ/NOPB, produced by Texas Instruments, is a low-power, multirate, 2-channel retimer designed to enhance the reach and robustness of high-speed serial links. This device features integrated signal conditioning, including a Continuous-Time Linear Equalizer (CTLE) and a Decision Feedback Equalizer (DFE), along with clock and data recovery (CDR) and transmit drivers on each channel. It is particularly useful in applications where lossy transmission media are present, such as in high-speed Ethernet and CPRI systems.
