The SY89834U is a high-speed, 1GHz 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 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
VCC/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.
