89H24NT24AG2ZBHLI

The 89H24NT24AG2ZBHLI is a high performance frequency synthesiser chip that is used as a Clock Generator, PLL and Frequency Synthesiser. It is designed to generate accurate, stable and reliable frequency outputs with low phase noise and jitter, suitable for many high-performance applications.

The 89H24NT24AG2ZBHLI frequency synthesiser has a reference input frequency range of 0-400 MHz, a maximum output frequency of 400 MHz and a noise floor below -122 dBc/Hz. It is also capable of synthesising square wave pulses and sine waves for precise timing, and has a low jitter of ±1.5ps RMS.

This frequency synthesiser chip has a wide range of applications, including timing and clocking for sensitive analog and digital circuits, variable frequency generator circuits, phase lock loop and frequency synthesiser application as well as in frequency synthesisers and PLL-based systems. It is typically used in crystal oscillator modules, frequency translators, frequency hopping and spread spectrum systems, routing switches, base stations and broadcasting transmitters.

In its simplest form, the 89H24NT24AG2ZBHLI operates by using an oscillator referenced to a quartz crystal to generate the reference frequency. This reference frequency is used to set the output frequency of the device. The PLL circuitry then locks onto this reference to ensure the output frequency remains stable over temperature, power supply and process variations. The frequency synthesiser also features an integrated loop filter and voltage regulator, allowing for easy and cost-effective setup and implementation.

The 89H24NT24AG2ZBHLI also includes a built-in frequency detector, or retimer, which enables the device to be automatically retuned in the event of a frequency change or drift. This retuning process ensures the device remains locked onto the reference frequency and reduces any phase noise or jitter which would otherwise be present. The retuning process is also able to handle a wide range of frequency variations to ensure the device remains locked on for the duration of the application, even when operating in challenging environments.

Overall, the 89H24NT24AG2ZBHLI is a very capable frequency synthesiser chip. Its ability to generate accurate, stable and reliable output with low phase noise and jitter make it a great choice for many high performance applications, while its integrated retuner and voltage regulator provide even more flexibility and performance.
