Description
A crystal controlled, high frequency,
highly stable oscillator, compatible with
Motorola 10KH,10KE or 100LVE logic
families. SaRonix proprietary fundamen-
tal high frequency sealed crystals avail-
able for exceptional stability and reliabil-
ity. The output can be disabled and wired-
OR for testing or combining multiple
clocks. Open emitter output allows the
user to select the load termination to
optimize performance. Complementary
outputs are available.*
Applications & Features
• Frequencies up to 250 MHz including
SONET/ATM/SDH 155.52 MHz
• Gigabit Ethernet
• Fibre Channel Hubs/Routers
• Ideal for high resolution graphics &
imaging applications
• 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
