Frequency control specialist, Euroquartz has introduced a new range of crystal oscillators (XO) from Greenray Industries Inc. that offer low phase noise and ultra-low acceleration sensitivity.
Housed in a compact, rugged 17.3mm x 17.3mm square package weighing less than 3 grams and suitable for hand or reflow soldering, the new RoHS-compliant Y1631 XOs offer sinewave output frequencies between 60 and 130MHz over an operating temperature range from -40 to +85°C. 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 2.0ppb/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 ideal for use in a wide range of industrial and defence-related applications including telecommunications, mobile radio, mobile instrumentation, airborne and wireless communications and microwave receivers.
Supply voltage requirement is 5V DC ±5% with supply current of 30mA. Additional specifications include frequency stability of ±15ppm from -20 to +70°C and ±20ppm from -40 to +85°C, ageing of ±1ppm in first year and ±3ppm over 10 years at 100MHz nominal frequency.
Euroquartz is an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the electronics manufacturing industry worldwide. The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers including major OEMs covering a broad spectrum of applications including defence and aerospace, communications, general electronics, computing, control systems and petrochemical among many others.
