CY2291FX Overview
In order to package it as a clock IC, the Tube package is used. This clock generator is embedded in the 20-SOIC (0.295, 7.50mm Width) package. The peak reflow temperature (Cel) amounts to 260 to be essentially indestructible. As a result, frequency synthesizers can be found to contain 20 terminations. To operate this time clock generator, 3.3V voltage should be applied. This clock generator receives its inputs from Clock, Crystal, which is designed to be the clock source. Using 1 circuits, the electronic part's full performance can be accessed. Providing a maximum frequency of 66.6MHz 90MHz, this clock-based RF synthesizer is suitable for a variety of applications. Surface Mount-slots make it easy to mount this electronic component on panels. In terms of supply voltage, RF synthesizer works with 3.3V 5V. Statistics suggest that the ambient temperature be set at 0°C~70°C, which is what is estimated by the test. The RF synthesizer is compatible with Clock, Crystal logic levels. An electrical part such as this one can be classified as a Clock Generator, Fanout Distribution component. Microprocessors are specifically designed to use this clock-generating IC, which has a 20-bit output. According to the base part number CY2291, its related parts can be found. The frequency synthesizer has 18 pins that are available. The supply voltage should be maintained at 5V for high efficiency. The device is usually classified as a type of Clock Generators device. This clock PLL features ALSO OPERATES AT 5V SUPPLY for better clock signal output. Clock PLL has 8 signal outputs to maximi8e output frequency. At frequencies of 90MHz, RF synthesizer achieves high efficiency. I have designed a clock PLL with 3 elements and low jitter performance.
