100ELT22
5V Dual TTL to Differential PECL Translator
General Description
The 100ELT22 is a TTL to differential PECL translator
operating from a single +5V supply.
Both outputs of a differential pair should be terminated in
50Ω to V
CC
- 2.0V even if only one output is being used. If
an output pair is unused both outputs can be left open
(un-terminated).
The 100 series is temperature compensated.
Features
a73 Typical propagation delay of 300 ps
