3.3V, DUAL DIFFERENTIAL
LVPECL-TO-LVTTL TRANSLATOR
SY100ELT23L
FEATURES
■ 3.3V power supply
®
Precision Edge
■ 2.0ns typical propagation delay
■ <500ps typical output-to-output skew
■ Differential LVPECL inputs
■ 24mA LVTTL outputs
DESCRIPTION
The SY10/100ELT23L are dual differential LVPECL-
to-LVTTL translators with +3.3V power supply. Because
LVPECL (Low Voltage Positive ECL) levels are used,
only +3.3V and ground are required. The small outline 8-
pin SOIC package and the low skew, dual gate design of
the ELT23L makes it ideal for applications which require
the translation of a clock and a data signal.
■ Flow-through pinouts
■ Available in 8-pin SOIC package
The ELT23L is available in both ECL standards: the
10ELT is compatible with positive ECL 10H logic levels,
while the 100ELT is compatible with positive ECL 100K
logic levels.
