ICS556-03

www.DataSheet4U.com ICS556-03 QUAD LVDS OSCILLATOR/BUFFER Description The ICS556-03 is a clock oscillator with quad LVDS outputs. Using a standard 25 MHz crystal, no additional external components are required to generate quad LVDS outputs at 25 MHz. This product is intended for clock generation. It has low output jitter (variation in the output period), but input to output skew and jitter are not defined nor guaranteed. Features Packaged in 16-pin TSSOP Requires no external components Low Phase Jitter: <1ps from 10 kHz to 10 MHz Quad, Differential LVDS outputs Operating voltage of 2.5 Volt Advanced, low-power, sub-micron CMOS process Block Diagram VDD EN1 EN2 EN3 EN4 CLKA CLKA CLKB 25MHz Crystal Oscillator CLKB CLKC CLKC CLKD CLKD LVDS GND MDS 556-03 B 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 030204 te l (40 8) 2 97-12 01 ● w w w. i c st . c o m ICS556-03 Quad LVDS Oscillator/Buffer Pin Assignment EN1 VDD A A B B EN2 X2 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 EN4 EN3 D D C C GND X1 16-Pin (150 mil) SOIC Pin Descriptions Pin Number 1 2 3 4 5 6 7 8 9 10 11 12 13 Pin Name EN1 VDD A A B B EN2 X2 X1 GND C C D Pin Type Input Power Output Output Output Output Input Input Input Power Output Output Output Pin Description Enable pin for Outputs A and A.
