DS21602SN is a product of CMOS voltage-controlled temperature-insensitive crystal oscillator (VC-TCXO). This crystal oscillator features a wide frequency range covering from 10MHz to 52MHz at standard frequency and 5MHz to 124MHz at half frequency version. It is widely used in precision clock control and other timing-sensitive applications due to its small size, low power consumption, and high stability.

This product offers frequency stability up to 0.05Y high frequency stability ranges over 0.37ppm to 0.52ppm, depending on the oscillating frequency; aging rate less than or equal to 5Y 10Y over the whole temperature range. It also offers low phase noise, low jitter, and excellent temperature characteristics for reliable performance.

The DS21602SN has various application fields. It is widely used in communications and media, such as timing modules and network equipment like routers, switches and optical transmitters. It is also used in wireless communication and 5G. The auto industry, such as the automobile, auto power supply, variable frequency air conditioning and automotive instrumentation, also uses DS21602SN.

Apart from that, DS21602SN is widely used in portable electronic products, such as mobile phones, smart watches, and access control systems. It is also applicable for the medical industry, such as bio-instrumentation and digital thermometers. Furthermore, it can be used in precision clocks, network equipment, digital television and other fields.

DS21602SN works in two ways to provide low frequency signal with temperature compensation. First, it utilizes the operating temperature to change the signal frequency. Secondly, it combines the effects of the temperature-insensitive crystal with the temperature-insensitive integrated circuit, used to regulate the frequency of the signal output. Moreover, it is internally integrated with its own temperature sensor and active loop frequency control circuit. The active loop creates a closed loop system which allows the oscillator to automatically adjust the frequency of its own oscillating circuit in order to hold the desired frequency established by the external control circuit. As a result, it can maintain power consumption even with temperature change, which also eliminates the need to adjust from time to time.

In conclusion, DS21602SN is a valuable component that offers frequency stability and low power consumption for its wide variety of applications. It is a reliable oscillator due to its excellent temperature characteristics and power consumption is low even when temperature change. It is useful for precision clockcontrol and other timing-sensitive applications.
