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.
