The SY89834U is a high-speed, 1GHz LVTTL/CMOS-toLVPECL 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 highspeed, low-skew fanout buffers, translators and clock generators.
