DESCRIPTION
The AZ10/100ELT22 is a dual CMOS/TTL to differential PECL translator. Because PECL (Positive ECL)
levels are used, only V
CC
and ground are required. The small outline packaging and the low skew, dual gate design
of the ELT22 makes it ideal for applications that require the translation of a clock and a data signal.
The ELT22 is available in both PECL standards: the 10ELT is compatible with PECL 10K logic levels while
the 100ELT is compatible with PECL 100K logic levels.
NOTE: Specifications in PECL tables are valid when thermal equilibrium is established.
