Introduction:
581L163X2ITT (581L) is an oscillator that belongs to the Oscillator family. It is a low power, temperature compensated crystal oscillator (TCXO) capable of generating an output frequency of up to 1.6GHz.

Application Field:
581L is a temperature compensated oscillator used for applications that require precise design and timing stability such as synchronization signals for SDH/SONET and cellular base station networks, frequency standards for digital and microwave communication systems, instrumentation for medical and industrial applications, and timing of clock and data recovery circuits. Moreover, this device has the capability for both manual tuning and automatic trimming, and can be used in both low power and high power applications.

Features:
581L oscillator features an output frequency range from 1MHz to 1.6GHz. It also features a frequency stability of ±25ppm over the entire operating temperature range of -40°C to+ 85°C. The power dissipation for this TCXO is only 4.0mW at 1.0V. It is available in a die configuration and also offers high frequency stability over the entire temperature range.It also features a low phase noise, low jitter and great startup time.

Working Principle:
581L oscillators utilize a temperature compensation circuit and crystal to produce a stable and reliable frequency output. The temperature compensation circuit utilizes a thermistor to monitor the temperature of the oscillator and correct the frequency output as the temperature changes. The output is then compared to a reference frequency using a voltage-controlled crystal oscillator (VCXO) circuit. The frequency output of the VCXO is then compared to a quartz reference oscillator, which is the base for the temperature compensation, and adjusted automatically by the PLL to maintain a stable and reliable output frequency.

Conclusion:
581L is a low power, temperature compensated crystal oscillator (TCXO) that is designed specifically for applications where precise and reliable timing is required. This device is capable of generating an output frequency up to 1.6GHz and has a frequency stability of ±25ppm over the entire operating temperature range. It features a low phase noise, low jitter and great startup time. Moreover, it also offers manual tuning and automatic trimming capability, making it ideal for use in both low power and high power applications.
