Part Numbering Guide
• Provides 10KH and 10KE (Motorola
ECLinPS) compatible outputs
• 3.3V PECL versions are LVDS com-
patible
• Disable/wired-OR output feature and
complementary output are available
• Superior stability with AT-cut crystal
performance compared to SAW tech-
nology
• Fundamental or overtone crystal op-
eration results in superior jitter charac-
teristics over PLL implementations
• Standard 0.200" high package
• Surface mountable gull wing version
available
