416F26025IKT

The 416F26025IKT is a 16-bit CMOS programmable frequency synthesizer designed for use in digital systems.

This device is designed to provide a source of high fidelity, low jitter and detuning performance in digital systems, with regard to phase noise, frequency stability and linearity. The technique used incorporates two types of phase-locked loops (PLLs).

The first loop, referred to as the main loop, comprises an oscillator, divider and phase detector. The phase detector senses the difference in phase between the input signal applied to the main loop and the main loop output. The divider can be programmed to divide the input signal frequency by any integer from 1 to 8, with the divided output being applied to the phase detector.

The second loop, referred to as the auxiliary loop, is used to control the frequency of the main loop. This auxiliary loop detects the timing difference between the output of the main loop and the clock frequency applied to the 416F26025IKT. The 416F26025IKT compares duty cycles and adjusts the duty cycle of the triggered output to maintain the desired frequency. This ensures stable output frequency over a wide temperature range.

The 416F26025IKT is suitable for use in digital systems applications, such as cell phones, automotive electronics, and digital TV and communications systems. It can be used to generate signals from a few MHz up to several hundred MHz with low jitter, frequency stability and linearity, while maintaining the phase noise performance of a standard frequency synthesizer. The 416F26025IKT therefore provides a robust, reliable and cost-effective means of delivering high fidelity signals.
