SiT9025中文资料1 to 150 MHz, AEC-Q100 Spread-spectrum Oscillator数据手册SiTime规格书

描述 Description

The SiT9025 is an industry’s first AEC-Q100-compliant, automotive-grade spread spectrum oscillator. This device solves EMI problems by offering two techniques for emissions compliance: spread spectrum clocking and rise/fall time adjustment of the clock signal. The SiT9025 is supported by SiTime’s Time Machine II programmer that allows designers to instantly program spread modulation and/or drive strength to quickly reduce emissions levels. What’s more, the SiT9025 comes in three industry-standard packages to replace quartz products without any board design changes. This combination accelerates time to revenue by ensuring emissions compliance with minimum engineering effort.
