Abstract

Over the last 3 decades the demands for increasing data transmission rates have driven the continual evolution of TTL backplane linedrivers. Each successive family has capitalized on the latest improvements in process, design and test technology. The ever improving electrical performance has been carefully characterized and recorded on the datasheet for comparison to earlier generations. ETL or “enhanced transceiver logic” is a departure from process driven technology but rather is a proposed backplane driver solution designed to meet the specific requirements of VITA, the International Trade Association whose charter is to ensure the success of the VMEbus. ETL offers improvements in three areas, those being incident wave switching even on very low impedance lines such as 25 ohms, improved noise immunity through tighter input thresholds, and hot insert capability without disruption of the bus. In addition, ETL is fully compatible with TTL I/O levels and the huge installed base of VME boards. This paper describes the unique features of ETL and application in a backplane such as VME
