DESCRIPTION
The SY89328L is a differential LVPECL-to-LVTTL
translator and an LVTTL-to-differential LVPECL translator
in a single package. Because LVPECL (Positive ECL) levels
are used, only +3.3V and ground are required. The
SY89328L is functionally equivalent to the SY100EPT28L,
but in an ultra-small 8-lead MLF™ package that features a
70% smaller footprint. This ultra-small package and the dual
translation design of the SY89328L make it ideal for
applications that are sending and receiving signals across
a backplane.
