85310I-11

Low Skew, 1-to-10 Differential-to-3.3V, 2.5V LVPECL/ECL Fanout Buffer 85310I-11 DATA SHEET General Description The 85310I-11 is a low skew, high performance 1-to-10 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer. The CLKx, nCLKx pairs can accept most standard differential input levels. The 85310I-11 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 85310I-11 ideal for those clock distribution applications demanding well defined performance and repeatability. Features Ten differential 2.5V, 3.3V LVPECL/ECL output pair Two selectable differential input pairs Differential CLKx, nCLKx pairs can accept the following interface levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL Maximum output frequency: 700MHz Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLK input Output skew: 30ps (typical) Part-to-part skew: 140ps (typical) Propagation delay: 2ns (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 -2.375V -40°C to 85°C ambient operating temperature Available in lead-free RoHS compliant package Block Diagram CLK0 Pulldown nCLK0 Pullup CLK1 Pulldown nCLK1 Pullup 0 1 CLK_SEL Pulldown CLK_EN Pullup D LE Q 85310I-11 Rev F 7/8/15 Q0 nQ0 Q1 nQ1 Q2 nQ2 Q3 nQ3 Q4 nQ4 Q5 nQ5 Q6 nQ6 Q7 nQ7 Q8 n...
