DUAL TTL-to-DIFFERENTIAL
PECL TRANSLATOR
SY10ELT22
SY100ELT22
FEATURES
DESCRIPTION
■ 300ps typical propagation delay
■ <100ps output-to-output skew
■ Differential PECL outputs
The SY10/100ELT22 are dual TTL-to-differential PECL
translators. Because PECL (Positive ECL) levels are
used, only +5V and ground are required. The small outline
8-lead SOIC package and the low skew, dual gate design
of the ELT22 makes it ideal for applications which require
the tranlation of a clock and a data signal.
■ PNP TTL inputs for minimal loading
■ Flow-through pinouts
The ELT22 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.
■ Available in 8-pin SOIC package
