TD-32.263MBE-T is a high accuracy, low-cost, and low-power digital, temperature-compensated, CMOS oscillator (TCXO).. It is a stand-alone oscillator with a wide frequency range. The oscillator operates minimally below 3.2V and consumes less than 30mA of current. It features an adjustable control voltage within a 10 MHz range and provides output signals in either sine wave, square wave, and voltage-controlled form.

Applications

TD-32.263MBE-T is widely used in various applications including cellular phones, cameras, personal digital assistants (PDAs), portable stereos and radio receivers. It is also used in embedded systems, clocks, satellite navigation and computer peripheral interfaces. In addition, it can be used in medical equipment, audio applications, instrumentation for industrial environments, and application-specific microprocessor designs.

Working Principle

The oscillator uses a temperature-compensated quartz oscillator circuit, which provides stability over temperature. The oscillator is composed of a hybrid integrated circuit and a quartz crystal resonator, as previously mentioned. The frequency of the oscillator is determined by the resonance of a quartz crystal, which is bond-wired to the integrated circuit. In normal operation, an oscillation device operates at a certain frequency, set by the oscillator’s Resonating frequency.

When a voltage is applied to the temperature-compensated quartz oscillator circuit, the frequency it produces will be determined by the controlling voltage applied to the control pin of the TCXO. The amplitude of the voltage applied to the control pin of the TCXO is known as the “control voltage.” In this case, the control voltage is set to steer the frequency of the TD-32.263MBE-T within a 10MHz range.

The TD-32.263MBE-T has an output of ±1ppm throughout operational temperature range, which is from -20°C to +70°C. Its input voltage is set to a range of 3.2V to 3.6V with a recommended operating voltage of 3.3V. The drive level is +2dBm and the rise time is less than 5ms.

The metal can package version of the TD-32.263MBE-T includes an optional frequency trimming feature that allows for an adjustable frequency range of ±10 ppm. In addition, the oscillator package includes an integrated power supply monitor circuit that provides information in the form of logic-level signaling regarding the input power supply voltage.

Conclusion

TD-32.263MBE-T is a CMOS oscillator that is well-suited for many different applications. It can be used as a stand-alone oscillator or as part of a larger system. It features a wide frequency range, temperature compensation, and adjustable voltage control. The metal can package version includes an optional frequency trimming feature and integrated power supply monitor. The oscillator is a low-cost, low-power solution that is suitable for a variety of embedded systems, clocks, satellite navigation, and computer peripherals.
