LOW SKEW, 1-TO-10 DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER
FEATURES
• 10 differential 2.5V/3.3V LVPECL / ECL outputs • 2 selectable differential input pairs • PCLKx, nPCLKx pairs can accept the following differential input levels: LVPECL, LVDS, CML, SSTL • Maximum output frequency: >3GHz • Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nPCLK input • Output skew: 20ps (typical) • Part-to-part skew: 85ps (typical) • Propagation delay: 495ps (typical) • Jitter, RMS: < 0.03ps (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.
