DESCRIPTION
The SY10/100EPT28L is a differential LVPECL-toLVTTL translator and a LVTTL-to-differential LVPECL 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.
