IQD’s new HGXO series of surface mount oscillators is designed primarily for military applications such as smart munitions and projectile electronics although the devices can also be used in demanding industrial applications. Designed around a hermetically sealed high-shock crystal and a CMOS compatible integrated circuit, the new device is able to survive shock levels of up to 100,000G and vibration levels of 20g at 10-2000Hz swept sine in accordance with MIL-STD-202G. Housed in an industry standard 7 × 5mm 4-pad ceramic package with metal lid, 5 supply voltage versions are available at 5.0V, 3.3V, 3.0V, 2.5V and 1.8V, thus providing compatibility with the latest generation of low power chipsets. Output frequencies can be specified between 460kHz and 50MHz with a 15pF HCMOS drive capability. Frequency tolerance is available down to ±10ppm whilst frequency stability can be specified at ±40ppm over the full military temperature range of -55 to 125°C down to ±10ppm over commercial temperature ranges coupled with low frequency ageing characteristics. The HGXO range is part of a comprehensive range of military specified products available from IQD covering both high specification crystals as well as oscillators. Full details are available from any of IQD’s sales offices.
