The device achieves \u00b150ppm frequency stability over the -20\u00b0C to +70\u00b0C operating range using a crystal-based resonator for low phase noise performance. The OCJ series offers an Enable\/Disable function with tri-state output, enabling system-level power management and clock gating. The D in the part number denotes the \u00b150ppm stability grade, C denotes CMOS output, and the J temperature grade covers -20\u00b0C to +70\u00b0C. The 4-SMD no-lead package (7.0 x 5.0 x 1.5mm) is compatible with standard surface-mount assembly. The device is RoHS3 compliant with MSL 1 rating.","working_principle":"The OCJTDCJTNF-125.00000 operates through three key subsystems:\n\n1. Crystal Resonator: An AT-cut quartz crystal operating in overtone mode provides the 125 MHz frequency reference. At this frequency, the crystal typically operates in its 3rd or 5th overtone mode, as fundamental mode crystals above 50 MHz become impractically thin. The overtone selection circuit ensures oscillation at the desired overtone rather than the fundamental.\n\n2. Oscillator and Limiter: The sustaining amplifier provides the gain required to maintain oscillation. An amplitude limiter circuit stabilizes the loop gain, preventing crystal overdrive that could cause frequency drift or accelerated aging. The oscillator circuit includes overtone mode selection components (LC tank) to suppress unwanted modes.\n\n3. CMOS Output Buffer: A CMOS output driver provides rail-to-rail output swing at 3.3V with symmetric rise\/fall times. The output buffer is designed to drive 15pF loads with minimal jitter. The Enable\/Disable function puts the output in tri-state (high-impedance) when disabled, allowing multiple oscillators to share a single clock line.","pin_description":"
