The SY89323L is a dual differential LVPECL-to-LVTTL

translator. Because LVPECL (Low Voltage Positive ECL)

levels are used, only +3.3V and ground are required. The

SY89323L is functionally equivalent to the SY100EPT23L,

but in an ultra-small 8-lead MLF™ package that features a

70% smaller footprint. The ultra-small package and the dual

gate design of the SY89823L make it ideal for applications

that require the translation of a clock and data signal in a

minimal space. The inputs are compatible with 10k and

100k input levels and any standard differential LVPECL

input referenced to a V
