The SY89834U is a high-speed, 2GHz LVTTL/CMOS-to-
LVPECL fanout buffer/translator optimized for high-speed
ultra-low skew applications. The input stage is designed to
accept two single-ended LVTTL/CMOS compatible signals
that feed into a 2:1 MUX. The selected input is translated
and distributed as four differential 100K compatible LVPECL
outputs. Within device skew is guaranteed to be less than
20ps over supply voltage and temperature.
The single-ended input buffers accept TTL/CMOS logic
levels. The internal threshold of the buffers is defined as
V
CC
/2
.
The SY89834U is a part of Micrel's high-speed Precision
Edge family. For applications that require a different I/O
combination, consult Micrel's website at
www.micrel.com
and choose from a comprehensive product line of high-
speed, low-skew fanout buffers, translators and clock
generators.
