SI4126-F-GMR Product Details

SI4126-F-GMR Overview


As a clock IC, it uses the Tape & Reel (TR) package. 28-VFQFN Exposed Pad contains this Clock PLL. This Clock PLL will be fed by Crystal as its input. There are 1 circuits implemented in order to achieve full performance from this electronic part. Providing a maximum frequency of 2.3GHz, 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 2.7V~3.6V different supply voltages that can be provided for this RF synthesizer. Based on test statistics, ambient temperature should be set at -40°C~85°C. 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 Frequency Synthesizer in this case. There is a 28 pin that is available on the digital clock generator. Despite its low operating temperature, this clock generator has -40°C operations. There is even a possibility that this clock generator ic will last even when the temperature is 85°C. The maximum supply voltage that clock generator can handle is 3V. 2 signal outputs allow for maximi2ation of output frequency. There can be no voltage higher than 3.6V when powering this frequency generator. This RF synthesizer can handle voltages as low as 2.7V.
