CXOXULPHT OSCILLATOR 32.768 kHz High Temperature/Ultra-Low Power/Fast StartUp/High Shock DESCRIPTION The CXOXULPHT 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 (55 µA), fast start-up time (2 ms), and a tight frequency stability (200 ppm) for high temperature operation up to +200OC. 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.
