CXOXULP OSCILLATOR 32.768 kHz Ultra-Low Power/Fast Start-Up/High Shock DESCRIPTION The CXOXULP 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 (17 µA), fast start-up time (2 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.

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 1 connected internally and so has no enable/disable capability. The following table summarizes the Enable/Disable option E.
