Clock signal generators are robust

WüRTH ELEKTRONIK WE-SPXO series quartz oscillators now includes a new design with LVDS or LVPECL output signal plus 32.768kHz oscillators. Devices are more temperature-stable and precisely optimized for specific requirements. Devices deliver output and frequencies from 100 to 156.25MHz (models IQXO-618-18, IQXO-618-33, IQXO-623 and IQXO-624) are designed for applications with higher data rates: Gigabit Ethernet, Fibre Channel, PCI Express and SONET/SDH. Products are available with differential LVDS or LVPECL output signal, and feature improved jitter performance and higher noise immunity of the output signal. Device’s temperature range of -40 to +105°C also exceeds the normal standards.
