CY2545QC021 Overview
As a clock IC, it uses the Tray package. 24-UFQFN Exposed Pad contains this Clock PLL. This Clock PLL will be fed by Clock, Crystal as its input. There are 4 circuits implemented in order to achieve full performance from this electronic part. Providing a maximum frequency of 166MHz, this clock-based RF synthesizer is suitable for a variety of applications. The Surface Mount allows this electrical component to be easily installed on the panel. There are 2.25V~3.6V different supply voltages that can be provided for this RF synthesizer. Based on test statistics, ambient temperature should be set at 0°C~70°C TA. I would like to present to you a frequency synthesizer that is compatible with Clock logic levels. This is an electronic part that can be classified as a Fanout Distribution, Fractional N Synthesizer, Multiplexer, Spread Spectrum Clock Generator in this case.
