Crystal Clock Oscillator Specification LFXO-AT 3.3V ISSUE 1; January 2016 Description Statek’s 32.768kHz surface mount LFXO oscillators, designed especially for applications requiring a fast start-up and high precision, consist of a Statek miniature AT quartz crystal and a CMOS/TTL compatible hybrid circuit in a ceramic package. Each crystal is pre-qualified before assembly into the oscillator through electrical tests and characterization over temperature. For harsh environments, a high shock version of the LFXO is also available.
