SI4133-D-GM Overview
As a clock IC, it is packaged by the Tray method. The 28-VFQFN Exposed Pad package embeds this Clock PLL. The frequency generator is capable of withstanding a maximum temperature of 260 during reflowing. As you can see, it consists of 28 terminations. Basically, this time clock generator needs a voltage of 3V. There is a Clock PLL called Crystal which is designed to be the input to this clock generator. Using 1 circuits, the electronic part's full performance can be accessed. RF synthesizers based on this clock provide frequencies up to 1.8GHz maximum. A Surface Mount-shaped electrical component makes it convenient to mount on a panel. A maximum voltage of 2.7V should be used for this frequency generator for safety reasons. There should be 2.7V~3.6V provided with this RF synthesizer. As determined by the test statistics, the ambient temperature should be set to -40°C~85°C. In this case, we are dealing with a frequency synthesizer that can be used with Clock logic levels. As far as this electronic part is concerned, it can be classified as a Frequency Synthesizer component. Microprocessor-specific clock PLL with 28 bits. The related electronic parts of part number SI4133 are listed below. There are 28 pins that are available on the clock PLL. RF synthesizers can handle a voltage of 3V as the supply voltage. High efficiency is achieved when operating at a frequency of 26MHz. I have designed a clock PLL with 3 elements and low jitter performance.
