ECL Pro SY10EPT28L 3V LVTTL-TO-DIFFERENTIAL LVPECL ECL ProSY100EPT28L Micrel, Inc. AND DIFFERENTIAL LVPECL-TO-LVTTL SY10EPT28L TRANSLATOR SY100EPT28L FEATURES 3.3V 10% power supply Guaranteed AC parameters over temperature: ECL Pro f > 275MHz (LVTTL) MAX < 2ns LVPECL-to-LVTTL propagation delay < 600ps LVTTL-to-LVPECL propagation delay DESCRIPTION Internal 75k input pull-down resistors The SY10/100EPT28L is a differential LVPECL-to- Industrial temperature range: 40C to +85C LVTTL translator and a LVTTL-to-differential LVPECL Available in 8-pin MSOP and SOIC packages translator in a single package. Because LVPECL (Positive ECL) levels are used, only +3.3V and ground are required. The small outline 8-pin package and the dual translation design of the EPT28L makes it ideal for applications which are sending and receiving signals across a backplane. The 100k series includes temperature compensation. Thus, logic levels are constant over temperature. Data sheets and support documentation can be found on Micrels web site at www.micrel.com.
