3.3V DUAL TTL-to-DIFFERENTIAL
PECL TRANSLATOR
FEATURES
DESCRIPTION
■ 3.3V power supply
The SY10/100ELT22L are dual TTL-to-differential
PECL translators with +3.3V power supply. Because
PECL (Positive ECL) levels are used, only +3.3V and
ground are required. The small outline 8-lead SOIC
package and the low skew, dual gate design of the
ELT22L makes it ideal for applications which require the
tranlation of a clock and a data signal.
The ELT22L 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.
■ 300ps typical propagation delay
■ <100ps output-to-output skew
■ Differential PECL outputs
■ PNP TTL inputs for minimal loading
■ Flow-through pinouts
■ Available in 8-pin SOIC package
