XOA91 - 32.768kHz oscillator with AT-Cut crystal

XOA91miniature oscillators consist of a TTL/CMOS-compatible hybrid circuit together with a miniature AT-Cut quartz crystal packaged in a low-profile, industry-standard ceramic package. The AT-Cut crystal provides high frequency stability but with a low µA current consumption, usually only available with a X-Cut crystal.
