Euroquartz offers a new range of crystal oscillators (XO) from Greenray Industries Inc that provide low-phase noise and ultra-low acceleration sensitivity.
Housed in a compact, rugged 17.3mm x 17.3mm square package weighing under 3g and ideal for hand or reflow soldering, the new RoHS-compliant Y1631 XOs provide sinewave output frequencies between 60MHz and 130MHz over an operating temperature range from -40C to +85C. Ultra-low phase noise at 100MHz nominal frequency ranges from -83dBc/Hz at 10Hz offset to -170dBc/Hz at 1MHz offset. Acceleration sensitivity – worst axis tested at 90Hz, 10g – is 2ppb/g as standard with low noise 0.5ppb/g and ultra-low noise 0.09ppb/g available to order. Shock screening is per MIL-STD-202, Method 213, while random vibration screening is per Method 214.
These new oscillators are excellent for a broad variety of industrial and defence-related applications, including telecommunications, mobile radio, mobile instrumentation, airborne and wireless communications and microwave receivers.
The supply voltage requirement is 5VDC ±5% with a supply current of 30mA. Further specifications include frequency stability of ±15ppm from -20C to +70C and ±20ppm from -40C to +85C, ageing of ±1ppm in the first year and ±3ppm over ten years at 100MHz nominal frequency.
