Saelig Introduces New 4-Pin Mil-Spec High Reliability Crystal Oscillators

Saelig Company 28 Years - RF Cafe

Saelig Intros 4-Pin Mil-Spec High Reliability Crystal Oscillators - RF CafeNovember 2, 2016 - Saelig Company, Inc. ( announces the EQXO-2000BM Mil-Spec High Reliability Crystal Oscillators - new 4-pin models which add to the recently launched range of Euroquartz military specification crystal oscillators designed for use in applications that require high reliability. The EQXO-2000BM's industry-standard '8-pin DIP oscillator' dimensions feature four active pins and a ruggedized three-point crystal mounting system. The new EQXO-2000BM series clock oscillators complement the previous 14-pin DIP models - EQXO-1000BMK and EQXO-3000BMK - launched earlier this year, which also incorporate a custom-designed quartz crystal and a CMOS/TTL compatible hybrid circuit on a ceramic substrate. Manufactured using the latest production techniques, these oscillators feature tight frequency calibration tolerance and high stability over a wide temperature range.

The available frequency range is from 30 kHz to 70 MHz with a calibration tolerance of ±10 to ±25 ppm at 25°C and a frequency stability of ±100 or ±50ppm over the full military temperature range (-55 to +125°C). Additional specifications include aging of ±3ppm maximum in the first year, symmetry of 45%/55%, and standard 5.0VDC supply voltage (other voltages on request). Standard output is CMOS, 50 pF/10 TTL loads, with other outputs available to special order.

Ideal for upper atmosphere, aerospace, defense and other applications where high-reliability clock oscillators are required, the new EQXO-2000BMK crystal oscillators can be screened to MIL-O-55310C, class B if required. Radiation tolerant EQXO-2000BMH versions will withstand ionizing radiation to resist electrical failures for a total radiation dose of 40krad(SI).

The EQXO-2000BM series oscillators are made by European frequency product specialist Euroquartz, an independent manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the worldwide electronics industry. The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers for military and aerospace, communications, general electronics, computing, control systems and petrochemical applications. These high reliability oscillators are available now from Euroquartz' USA distributor Saelig Company. Inc.

Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
