Ideal for high temperature environments, the 32.768kHz CXOXHT and CXOMHT oscillators provide a fast start-up time (0.8ms typical) and tight frequency stabilies over temperature to 200°C. The parts will withstand high shock

The CXOMK quartz crystal oscillator is the successor to the long-established and successful CXOM/CXO3M oscillator range. The part is form, fit and function compatible with these oscillators, sharing the same footprint and 5.0 mm by 6.5 mm outline. The CXOMK uses a metal-to-metal weld that makes it more resistant to the high temperatures seen during solder reflows. Thanks to advanced production technologies the CXOMK oscillator is capable of achieving frequency accuracies of ±30 ppm over -40°C to +85°C or ±40 ppm over -55°C to +125°C. The CXOMK is available at operating voltages from 0.9V to 5.0 Volts. Full MIL testing is available if required.

High shock survivability High frequency stability Low acceleration sensitivity (HG version) CMOS and TTL compatible Low power consumption Full military testing per MIL PRF 55310 available Optional enable/disable Low EMI emission Hermetically sealed ceramic package

CXOX oscillators are ultra-miniature, surace-mount units packaged in a 3.40mm x 2.70mm package. The part has good shock and vibration survivability characteristics and may also be ordered as a high shock (HG) unit with shock survivability of 10,000g. The oscillator may be specified at any operating temperature range from commercial, -10 to +70°C to full MIL, -55 to +125°C. Full MIL testing is available.

The ultra-miniature 32.768kHz CXOX oscillators provide a fast start-up time (0.6ms) and tight frequency stability (±30ppm to ±100ppm) over a wide temperature range (-55° to +125°C). The part will withstand significantly higher shock than other oscillators using tuning fork-design crystals. The part has an optional enable/disable function. Full MIL testing is available.

CXOXHT oscillators are ultra-miniature, SMD units packaged in a 3.40mm x 2.70mm package. The part is designed for extended periods of high temperature operation, up to 225°C, conditions such as those experience by 'downhole' instrumentation, rotary shaft sensors and underground boring tools. The part has high shock and vibration survivability characteristics and may also be specifically ordered as a high shock (HG) unit with shock survivability of 10,000g. The oscillator may be specified at any operating temperature range from -55°C to +225°C

The ultra-miniature 32.768kHz CXOXULP oscillators use an AT-Cut crystal for tight stability and also have a low current consumption, typically 15µA. A fast start-up time (15ms) and tight frequency stability (±30ppm to ±100ppm) over a wide temperature range (-55° to +125°C). The part will withstand significantly higher shock than other oscillators using tuning fork-design crystals. The part has an optional enable/disable function. Full MIL testing is available.
