Housed in a compact 3.2 x 2.5 x 0.9 mm ceramic package, it combines a high-Q AT-cut quartz crystal with temperature compensation circuitry to deliver precision timing references for wireless communication systems, GNSS receivers, smart metering modules, and industrial measurement equipment.","working_principle":"The TG3225CEN uses an AT-cut quartz crystal resonator as the frequency-determining element, combined with a temperature compensation network that generates a correction voltage to counteract the crystal's inherent frequency-temperature characteristic. The compensation circuit includes a temperature sensor, correction voltage generator, and varactor diode that adjusts the crystal's load capacitance to maintain the output frequency within \u00b12.0 ppm over the full operating temperature range. The oscillator output is shaped to CMOS logic levels (90% Vcc high, 10% Vcc low) with rise\/fall times under 8 ns, suitable for direct connection to digital IC clock inputs.","pin_description":"
