LOW SKEW, DUAL, 1-TO-5 DIFFERENTIAL-TO-2.5V/3.3V ECL/LVPECL FANOUT BUFFER
FEATURES
• 2 differential 2.5V/3.3V LVPECL / ECL bank outputs • 2 differential clock input pairs • CLKx, nCLKx pairs can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL • Maximum output frequency: 700MHz • Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLKx input • Output skew: 25ps (typical) • Part-to-part skew: 270ps (typical) • Propagation delay: 1.7ns (typical) • Additive phase jitter, RMS: <0.13ps (typical) • LVPECL mode operating voltage supply range: VCC = 2.375V to 3.8V, VEE = 0V • ECL mode operating voltage supply range: VCC = 0V, VEE = -3.8V to -2.
