Overview
The DS100DF410SQE/NOPB, produced by Texas Instruments, is a low-power 10GbE quad-channel retimer designed to support high-speed data transmission. This device integrates advanced signal conditioning features, including a Continuous-Time Linear Equalizer (CTLE), Clock and Data Recovery (CDR), and a Decision Feedback Equalizer (DFE) to enhance signal integrity over long, lossy, and crosstalk-impaired serial links. Each channel can independently lock to a 10.3125 Gbps data rate, making it suitable for 10GbE applications. The retimer is packaged in a 48-pin WQFN (RHS) package and operates within a temperature range of -40°C to 85°C.
