CY26121ZI-21T Overview
As a clock IC, it is packaged by the Tape & Reel (TR) method. The 16-TSSOP (0.173, 4.40mm Width) package embeds this Clock PLL. The frequency generator is capable of withstanding a maximum temperature of 225 during reflowing. As you can see, it consists of 16 terminations. Basically, this time clock generator needs a voltage of 3.3V. There is a Clock PLL called Clock, 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 33.33MHz maximum. A Surface Mount-shaped electrical component makes it convenient to mount on a panel. There should be 3.135V~3.465V 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 Fanout Distribution, Multiplexer, Spread Spectrum Clock Generator component. Microprocessor-specific clock PLL with 16 bits. The related electronic parts of part number CY26121 are listed below. There are 16 pins that are available on the clock PLL. RF synthesizers can handle a voltage of 3.3V as the supply voltage. There is an electronic part in this series that belongs to the PacketClock™ family. The output frequency can be magnified as high as possible with the assistance of 5 signal outputs. High efficiency is achieved when operating at a frequency of 25MHz.
