Clock generators, PLLs, and frequency synthesizers are popular circuit components used in devices that require timing and synchronization capabilities. The 841202AK-245LFT is a frequency synthesizer, specifically tailored to be used in radio broadcasting and telecommunication projects such as digital television, radio transmitters, and digital audio broadcasting. This device uses a Phase Locked Loop (PLL) circuit to generate a stable, precise output frequency in the range of 2.4GHz to 2.5GHz.

At the heart of the 841202AK-245LFT frequency synthesizer is a PLL circuit. A PLL works by comparing the phase of a reference signal to its own output frequency to generate a control voltage. This voltage is used to adjust the frequency of the output signal to match the reference signal. The reference signal is generated from an external source, and for the 841202AK-245LFT this is typically a crystal oscillator. By using the PLL, the 841202AK-245LFT is able to generate a stable output frequency from a wide range of input frequencies, without having to physically adjust the components of the circuit.

The 841202AK-245LFT has adjustable frequency dividers and low pass filters to fine-tune the output frequency. The dividers allow the output frequency to be divided by any number between 2, 4, 8, 16, 32, 64, 128 and 256, while the low pass filters are used to reduce the amount of noise in the output frequency. These adjustable components allow the frequency synthesizer to be optimized for the application being used. For example, the dividers and filters can be adjusted to generate a frequency range of 2.45GHz to 2.5GHz with a low noise floor, which is ideal for radio broadcasting.

The 841202AK-245LFT is designed for applications that require a high stability output. The PLL provides a locking range of 8.4kHz to 8.9kHz, which ensures the output frequency will remain stable and accurate even in the presence of external noise or interference. Additionally, the frequency synthesizer is temperature compensated, meaning it can maintain its accuracy even in temperatures of up to 85°C. This makes the 841202AK-245LFT an ideal choice for applications in high temperature environments.

Overall, the 841202AK-245LFT frequency synthesizer is an ideal choice for projects that require a stable output frequency in the range of 2.4GHz to 2.5GHz. It is highly accurate, reliable and temperature compensated, making it suitable for applications such as radio and digital television broadcasting, radio transmitters, and digital audio broadcasting.
