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.
