DESCRIPTION
The SY100EPT23L 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 tiny 8-pin MSOP and dual-gate design of the EPT23L
makes it ideal for applications which require the
translation of a clock and data signal.
The EPT23L is available in only the ECL 100K
standard. Since there are no LVPECL outputs or an
external V_BB reference, the EPT23L does not require
both ECL standard versions. The inputs can accept 10K
voltage levels and any standard differential LVPECL input
referenced from a V_CC of +3.3V
