CXOLAT OSCILLATOR 32.768 kHz Ultra-Low Power/Fast Start-Up/Ultra-Miniature DESCRIPTION The CXOXLAT 32.768 kHz oscillator achieves the low power comparable with a tuning fork design and the fast start-up and tight frequency stability attained by an AT cut crystal design. Designed for applications requiring ultralow current (15 µA), fast start-up time (15 ms), and a tight frequency stability (±30 ppm to ±100 ppm) over a wide temperature range (-55OC to +125OC). These oscillators are also capable of withstanding significantly higher shock than a standard tuning fork design. FEATURES Ultra-low current (typical 15 µA) DIMENSIONS Fast start-up (typical 15 ms) Tight tolerance High shock resistance Low aging CMOS output Optional Output Enable/Disable with Tri-State Hermetically sealed ceramic package Full military testing available Designed and manufactured in the USA TYPICAL DIM inches mm MAXIMUM inches mm A 0.126 3.20 0.130 3.30 B 0.059 1.50 0.063 1.60 C (SM1) 0.037 0.95 0.039 1.00 Communications D 0.029 0.75 0.030 0.77 Navigation E 0.020 0.50 0.021 0.52 APPLICATIONS Military, Aerospace & Avionics GPS Industrial, Computer & Communications Handheld instrumentation Transponder/Animal migration SUGGESTED LAND PATTERN PIN CONNECTIONS 1.

The E-version has a TriState output and stops oscillating internally when the output is put into the high Z state. The N-version does not have PIN 3 connected internally and so has no enable/disable capability. The following table summarizes the Enable/Disable option E. 20 g, 10-2,000 Hz swept sine Vibration 3 Operating Temp.
