Electronica 2010 – Flaunted as the smallest low G-sensitivity oscillators for military applications and other harsh environments the 508-series clocks and oscillators include a rugged four-point mount crystal. Each component is said to achieve industry-leading noise performance in an extremely small 9 x 14 package. The PX-508 XO specs a stability range from ±40 ppm (-55°C to +105°C) to ±15 ppm (-20°C to +70°C) while the VX-508 VCXO offers a stability range of ±40 ppm (-55°C to +105°C) to ±15 ppm (-20°C to +70°C). Additionally, the TX-508 TCXO has a stability range of ±0.8 ppm (-40°C to +85°C) to ±0.28 ppm (-20°C to +70°C). VECTRON INTERNATIONAL, Hudson, NH. (888) 328-7661.
