Description
A crystal controlled, high frequency,
highly stable oscillator, compatible with
Motorola 10KH,10KE or 100LVE logic
families. The output can be disabled and
wired-OR for testing or combining mul-
tiple clocks. Open emitter output allows
the user to select the load termination to
optimize performance. Complementary
outputs are available.
Applications & Features
• SONET/ATM/SDH - 155.5200 MHz
• Forward Error Correction (FEC) -
166.6285 MHz
• Gigabit Ethernet - 125.0000 MHz
• Fibre Channel - 106.2500 MHz
• 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
• True SMD DIL 14 version available
