ICS556-04

www.DataSheet4U.com ICS556-04 LOW SKEW 1 TO 4 CLOCK BUFFER Description The ICS556-04 is a low-skew, crystal input compatible clock buffer with oscillator. This device offers the lowest skew. See the ICS552-02 for a 1-to-8 low skew buffer. For more than eight outputs see the MK74CBxxx BuffaloTM series of clock drivers. ICS makes many non-PLL and PLL-based low-skew output devices. Contact ICS for all of your clocking needs. Features Extremely low-skew outputs (50 ps maximum) Packaged in 8-pin SOIC Operating voltages of 2.5 to 5.0 V Low-power CMOS technology Industrial temperature range Available in Pb (lead) free package Block Diagram Q0 5 to 27 MHz Crystal or clock X1/ICLK Q1 Crystal Oscillator/ Buffer Q2 Q3 X2 Optional crystal capacitors MDS 556-04 C I n t e gra te d C i r c u i t S y s t e m s ● 1 525 Race Stre et, San Jo se, CA 9 5126 ● Revision 030905 te l (40 8) 2 97-12 01 ● w w w. i c st . c o m ICS556-04 LOW SKEW 1 TO 4 CLOCK BUFFER Pin Assignment VDD X 1 / I CL K X2 GN D 1 2 3 4 8 7 6 5 Q4 Q3 Q2 Q1 8 - p i n ( 1 5 0 mi l ) S OI C Pin Descriptions Pin Number 1 2 3 4 5 6 7 8 Pin Name VDD X1/ICLK X2 GND Q1 Q2 Q3 Q4 Pin Type Power Input Input Power Output Output Output Output Pin Description Connect to +2.5 V, +3.3 V or +5.0 V.
