SahRonrix Crystal Clock Oscillator 3.3 & 5V, High Frequency, ECL Technical Data SEL2400 / SEL3400 Series ACTUAL SIZE Description A crystal controlled, high frequency, highly stable oscillator, compatible with Motorola 1OKH,10KE or LOOLVE 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 e 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 1OKH 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 e * For internal termination contact factory. Frequency Range: 7 MHz to 250 MHz Frequency Stability: 20, +25, 50 or +100 ppm over all conditions: calibration tolerance, operating temperature, input voltage change, load change, aging, shock and vibration.
