New ruggedised clock oscillators with extended industrial temperature range

Euroquartz has launched a new range of UK manufactured surface mount ruggedised clock oscillators providing an extended industrial operating temperature range from -40C to +105C. These products are manufactured in the company's cleanroom facility and are free of ITAR restrictions.

Offered on short lead times, the new EQXO-75UIE series crystal oscillators provide high-reliability in a standard format 7mm x 5mm SMD ceramic package with hermetically sealed metal lid. Designed by the company particularly for demanding industrial applications, the series components offer reliable operation with good frequency stability over an extended industrial temperature range with mechanical shock survivability tested to 1500g (MIL-STD-883K Method 2002.5, Condition B). Temperature stability specification options provided are ±50, ±75 and ±100ppm with tighter options upon request.

Offered with superior phase noise performance of -164dB/Hz (typical) at 100kHz and femtosecond integrated phase jitter of 150fs typical (12kHz to 20MHz integrated), the devices are provided in frequencies ranging from 2HMz to 60MHz.

The new ruggedised components provide supply voltage options of 2.5V and 3.3V (±10%) or 5V (±5%). Further specifications include LVCMOS output logic, 15pF load, rise time of 10ns maximum, start-up time of 3ms maximum, and enable/disable function as standard. Current consumption is 6mA to 16mA maximum depending on frequency. Ageing is ±1ppm maximum for the first year with standard pre-age bake beyond 96 hours at 100C and custom crystal pre-ageing options available. Solder profile is 260C max.
