  Understanding EEPROM Programming for High Speed Repeaters and Mux Buffers
  PDF, 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
