MMD Adds Line of Military-Grade TCXOs
RANCHO SANTA MARGARITA, Calif., October 31, 2006 - MMD Components (Monitor & Quartztek), a producer of frequency control devices, has introduced a series of military-grade temperature-compensated crystal oscillators (TCXOs) that have been tested and screened per MIL-PRF-55310 and MIL-STD-883 Class B standards.
For radiation tolerance, the new TCXOs are rad-hardened to 20 K. Moreover, they can withstand swept sine vibration of 20 G's, 10 Hz to 500 Hz, and mechanical shock of 500 G's, half-sine pulse @ 0.1 milliseconds, 3 axis; MMD can also accommodate a customer's more stringent requirements.
The units can maintain a frequency stability of 1 ppb over an ultra-wide operating temperature range of -55ºC to +125ºC, using proprietary compensation and stabilization methods. Customers can specify sine wave, HCMOS, TTL or PECL output; a frequency range of 1 MHz to 100 MHz; and an input of 3.3, 5, 12 and 15 volts. Custom frequencies and input voltages are also available.
The TCXOs come in a variety of packages - 14-pin DIL (dual in-line), 1 x 1 inch, and 9 x 14 millimeters - and custom packages can be specified.
Availability for the new military-grade TCXOs is stock to 18 weeks, with prices starting at $85 each in 100-unit quantities. More information can be obtained from MMD Components (Monitor & Quartztek), 30400 Esperanza, Rancho Santa Margarita, Calif., 92688; telephone 949-753-5888 or, toll free, 877-663-2667; e-mail firstname.lastname@example.org; or on the Web at www.mmdcomp.com.
