Description
A crystal controlled, high frequency,
highly stable oscillator, compatible with
Motorola 10KH,10KE or 100LVE logic
families. SaRonix proprietary high fre-
quency sealed crystals running on the
fundamental or 3rd overtone available
for exceptional stability and reliability.
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
• Ideal for high resolution graphics &
imaging applications
• Superior stability with AT-cut crystal
performance compared to SAW tech-
nology
• Provides 10KH and 10KE (Motorola
ECLinPS) compatible outputs
• 3.3V PECL version with 10LVE out-
puts
• Frequencies up to 250 MHz including
SONET 155.52 MHz
• Disable/wired-OR output feature avail-
able
• Standard 0.200" high package
• Fundamental or overtone crystal op-
eration results in superior jitter charac-
teristics over PLL implementations
• AT crystal technology allows for eco-
nomic and quick turn-around of cus-
tom frequencies
• Surface mountable gull wing version
