SIT1602BI-81-28N-33.333330T

Oscillators can be broadly categorized into two sections, Electro-mechanical and Electronic Oscillators. SIT1602BI-81-28N-33.333330T falls into the second category of electronic oscillators. It is a voltage-controlled crystal oscillator (VCXO) that is designed specifically for cellular applications.

SIT1602BI-81-28N-33.333330T is a high frequency type of VCXO and offers a wide range of frequencies. With frequency range of 19.2MHz to 39.6MHz, it is able to fulfill a variety of applications in the cellular communication market such as digital base station equipment and mobile handset transceiver specifications. The output frequency stability can be as low as ±3.0ppm as long as -20 to +70 degree Celsius is maintained.

The working principle of SIT1602BI-81-28N-33.333330T is quite simple. It utilizes a crystal and a comparator that works in conjunction with a temperature-compensating capacitor to establish and sustain oscillations, and uses a voltage-controlled phase shifter and charge pumps to adjust the frequency. This architecture enables it to achieve the stability and control of the voltage.

The output voltage ranges from 0.6V to 2.8V. It also features a “tune rise time” setting where an increasing phase shift of the output waveform produces fast rise time with low jitter. It enables the device to be connected directly to a frequency divider for fast transitioning and settling of the output frequencies.

In addition, SIT1602BI-81-28N-33.333330T comes with features such as an inhibit function and rising edge enable/ disable function. It also features a useful temperature-stabilizing compensation circuit that helps to minimize the variations in temperature dependence from part to part.

For applications such as point-to-point radios, wideband radios, or digital base station equipment, SIT1602BI-81-28N-33.333330T is the ideal choice due to its features and excellent frequency-stability. The wide variety of frequencies and features ensures that it is capable of meeting the demanding requirements of today\'s cellular communication market.
