MICROCHIP SY89834UMI-TR

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.

• Selects between two LVTTL/CMOS inputs and provides 4 LVPECL output copies
• Guaranteed AC performance over temperature and voltage: DC-to >1.0GHz throughput <500ps propagation delay (IN-to-Q) <20ps within-device skew <225ps rise/fall time
• Ultra-low jitter design: <1psRMS cycle-to-cycle jitter <1psRMS random jitter <10psp-p deterministic jitter <10psp-p total jitter (clock)
• Low voltage 2.5V and 3.3V supply operation
