402F36022ILT

A402F36022ILT device is an integrated crystal device (IC). It is a low-power, low-cost device that integrates an oven-controlled crystal oscillator (OCXO) and temperature controller. The device provides precise frequency-stability up to 10 kHz and excellent shock and temperature-drift performance.

The main application of the 402F36022ILT device is in wireless communication systems where it provides high-performance frequency stability to enable precise control of baseband signals. The device finds many applications in consumer electronics, automotive and industrial instrumentation.

The building block of a 402F36022ILT device is an OCXO, which is a type of oscillator that uses a crystal material as its coupling element and a heater to keep it stable over a range of operating temperature. A crystal is an ideal electrical resonator that oscillates at a precise frequency when it is excited by an electrical current. By stretching or compressing the crystal element, it can be controlled to oscillate at specific frequencies to minimize the frequency drift with respect to temperature over a wide temperature range.

The OCXO employs a thermally isolation cavity as the housing, which is capable of dissipating the thermal energy generated by the heater and ensuring that only a minimal amount of thermal energy is transmitted to the crystal element. This guarantees a high level of frequency stability against environmental temperature changes. The high thermal isolation of the cavity coupled with a precise temperature controller allows for precise regulation of the crystal frequency even in extreme environmental conditions.

The temperature controller in the device comprises of a thermocouple, a thermistor and a heat sink on the quartz crystal. The thermistor measures the temperature of the crystal and sends a signal to the temperature controller, which then adjusts the voltage of the heater to keep the crystal at a constant temperature. By carefully controlling the voltage of the heater and the temperature of the crystal, the 402F36022ILT device can achieve a high stability and accuracy and meet the exacting requirements of wireless communication systems.

The 402F36022ILT device therefore can be used in many applications where precise frequency stability is required such as wireless basestation, GPS receivers, satellite communication and wireless local area networks. By providing high-performance frequency-stability, the 402F36022ILT device enables efficient control and operation of complex basestation electronics and communication systems.
