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