Low Skew, 1-to16, Differential-to-3.3V ICS8530-01 LVPECL Fanout Buffer DATA SHEET General Description Features The ICS8530-01 is a low skew, 1-to-16 Differential-to-3.3V LVPECL Sixteen differential 3.3V LVPECL outputs Fanout Buffer. The CLK, nCLK pair can accept most standard CLK, nCLK input pair differential input levels. The high gain differential amplifier accepts CLK, nCLK pair can accept the following differential input peak-to-peak input voltages as small as 150mV as long as the levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL common mode voltage is within the specified minimum and Maximum output frequency: 500MHz maximum range. Translates any single-ended input signal to 3.3V LVPECL levels Guaranteed output and part-to-part skew characteristics make the with a resistor bias on nCLK input ICS8530-01 ideal for those clock distribution applications Output skew: 75ps (maximum) demanding well defined performance and repeatability. Part-to-part skew: 305ps (maximum) Additive phase jitter, RMS: 0.03ps (typical) Full 3.3V supply voltage 0C to 70C ambient operating temperature Available in both standard (RoHS 5) and lead-free (RoHS 6) packages Block Diagram Pin Assignment Pulldown CLK Pullup nCLK 48 47 46 45 44 43 42 41 40 39 38 37 Q0 Q15 VCCO CLK 1 36 Q11 2 35 VCCO nQ15 nQ0 nQ11 3 34 nQ0 Q1 Q14 Q10 4 Q0 33 nQ10 5 32 nQ1 nQ1 nQ14 VEE Q1 6 31 Q2 Q13 Q9 VEE 7 30 nQ13 nQ9 8 29 nQ2 nQ2 Q8 Q2 9 28 Q12 Q3 nQ8 10 nQ3 27 nQ3 nQ12 VCCO 11 26 Q3 VCC 12 VCCO 25 Q11 Q4 13 14 15 16 17 18 19 20 21 22 23 24 nQ11 nQ4 Q5 Q10 ICS8530-01 nQ5 nQ10 48-Lead LQFP Q6 Q9 7mm x 7mm x 1.4mm package body nQ9 nQ6 Y Package Q8 Q7 Top View nQ8 nQ7 ICS8530FY-01 REVISION G NOVEMBER 15, 2012 1 2012 Integrated Device Technology, Inc.
