This report summarizes the results of SAS/SATA testing using TI’s DS125BR820 and DS125BR401A Low-Power 12.5 Gbps 8-Channel Repeaters. The TI devices are tested in an external miniSAS-HD environment and directly using a DS125BR820EVM. The test results will demonstrate how linear equalization can improve system margin and allow for the extended channel configurations that are required in the latest - Channel Tuning Made Easy Using Linear Repeaters for 10G and 12G ApplicationsPDF, 3.4 Mb, File published: Jan 20, 2015
This report demonstrates the benefits of using Texas Instruments Linear Redrivers to simplify the process of channel tuning and improve system margins. Test results of the DS125BR820 linear redriver operating in various pre-channel and post-channel conditions are presented and show improvements in channel conditions in terms of transmitter pre- and post-cursor error-free operat - Analog Applications Journal 2Q 2015PDF, 2.5 Mb, File published: Apr 28, 2015
- Understanding EEPROM Programming for High Speed Repeaters and Mux BuffersPDF, 317 Kb, File published: Oct 9, 2014
System designers often use EEPROM (Electrically Erasable Programmable Read-Only Memory) to program a set of customized high speed repeater and mux buffer start-up settings that are different from the default. Using the information here will make repeater EEPROM configuration and programming easy to implement and understand. This application note addresses SMBus-to-EEPROM mapping for 2-channel repe
