The 39MHz frequency is a standard reference for GPS\/GNSS receivers where the local oscillator must maintain tight frequency accuracy for satellite signal acquisition and tracking. The TCXO uses a compensation network that adjusts the oscillator frequency based on temperature, counteracting the crystal's inherent frequency-temperature characteristic. The clipped sine wave output provides a clean clock signal with low harmonic content suitable for direct RF mixer injection. Housed in a compact 3.2 x 2.5 x 1.0mm ceramic SMD package, the TG3225CEN consumes only 2.5mA from a 2.8V supply, making it ideal for battery-operated GNSS devices.","working_principle":"The TG3225CEN TCXO combines an AT-cut quartz crystal resonator with a temperature compensation circuit to maintain \u00b10.5ppm frequency stability. A temperature sensor (typically a thermistor network) measures the ambient temperature and generates a compensation voltage that adjusts the varactor diode capacitance in the crystal oscillator circuit. This capacitance adjustment shifts the oscillator frequency to counteract the crystal's parabolic frequency-temperature characteristic (approximately -0.035ppm\/\u00b0C\u00b2 for AT-cut crystals). The compensation polynomial is factory-trimmed for each individual oscillator during production. The output stage converts the oscillator signal to a clipped sine wave, which provides the spectral purity needed for RF applications while maintaining low current consumption. The 3ms start-up time is achieved through optimized oscillator loop gain and crystal drive level.","pin_description":"
