DESCRIPTION
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_CC of 3.3V.
