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
