Euroquartz expands portfolio with Greenray crystal oscillators
Frequency control specialist, Euroquartz has introduced a range of crystal oscillators from Greenray Industries. The crystal oscillators offer low phase noise and low acceleration sensitivity, confirmed Euroquartz.
The crystal oscillators are housed in a compact and rugged 17.3 x 17.3mm square package weighing less than 3.0g which is suitable for hand or reflow soldering.
The RoHS-compliant Y1631 crystal oscillators offer sinewave output frequencies between 60 and 130MHz over an operating temperature range from -40 to +85 degrees C. 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 2.0ppb/g as standard with low noise 0.5ppb/g and 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.
The Y1631 oscillators are suitable for use in a range of industrial and defence-related applications including telecommunications, mobile radio, mobile instrumentation, airborne and wireless communications and microwave receivers.
The supply voltage requirement is 5.0V DC ±5 per cent with supply current of 30mA. Additional specifications include frequency stability of ±15ppm from -20 to +70 degrees C and ±20ppm from -40 to +85 degrees C, ageing of ±1ppm in the first year and ±3ppm over 10 years at 100MHz nominal frequency.
