The 8421002AGI-01LFT clock generator-phase locked loop (PLL) chip is a highly efficient programmable frequency synthesizer that is designed for use in a wide range of applications, ranging from high-frequency modulation and control to sophisticated embedded systems and portable instrumentation. The device has the ability to divide a reference frequency (such as a crystal oscillator) by up to 64 times, producing a stable output frequency within a certain range, as well as optionally providing a selectable divide by 4 (observed at the output divider) or 16 (observed at the output divider). It can also provide the output frequency through a pulse-width-modulated (PWM) signal, or a variable rate clock generator, which can be used for a variety of applications.

The 8421002AGI-01LFT provides a low cost, low-power clock generator solution for any embedded application, from toys and gizmos, to broadcast instrumentation and communications systems. It includes a wide range of features, including a pre-divider, frequency dividers (from 1 to 64), post-divider, programmable delay, PLL loop filter, adjustable voltage controlled oscillator (VCO), RSSI and Amplitude Detector, voltage-controlled current sources, and pulse-width modulation (PWM). In addition, the device provides the ability to control the phase of the output frequency to an accuracy of ± 5%, using the integrated buffer and phase shifting control loop.

The 8421002AGI-01LFT features a wide range of programmable features, allowing users to customize their applications. It provides a wide range of frequency flexibility, allowing for a wide range of output frequency settings, from under 10 to over 1 million Hz. In addition, a built-in Fractional-N divider allows users to adjust their output frequency to a much higher precision, with the ability to program a frequency step as low as 4 PPM. The device also includes an RSSI (receive signal strength indicator) and Amplitude Detector, allowing users to detect small signals as low as 10mV into the device.

The 8421002AGI-01LFT operates on a 3.3V or 5.0V supply, drawing a maximum of 165mA, making it suitable for use in mobile and space constrained applications. The device is also designed to be ESD protected, ensuring a long operational life in a variety of electrically hazardous environments. The 8421002AGI-01LFT can be used in a wide range of clock/timing applications, including embedded system clocks, clock generators, modulator systems, and frequency synthesizer systems.
