ATS2819/ATS2819P标准应用方案主要分为以下功能模块:Power Supply,BlueTooth,Audio Input/Output(包括codec、I2C、SPDIF),FM Receiver,disaplay(LED&LCD),USB,SPI Nor Flash Memory,SD/MMC/MS Card等。1.2原理图设计总体原则1原理图设计需要按照方案规格的要求实现各项硬件功能,尽量避免功能模块相互间的资源冲突。如果存在I/O复用,接收复用等情况,除了需注意检查I/O上电状态,接口时序等,还需要注意复用的SIO工作频率与工作电压域是否符合要求(如WIO),确保功能设计正确实现。2原理图设计要求性能达到要求。如稳定性,启动电压,功耗,ESD,EMI等。要注意检查模块电源开关状态,选择的原件标称及精度、材质,接口保护元件和EMI滤波器等。3系统时钟26MHZ,要求CL为7~9PF,精度为+-10PPM。这样才能保证系统能正常工作。4当设计PCB受限于模具大小时,各个模块无法保证均能得到最优的布局布线(如滤波电容要求靠近IC、走线上要求尽量少的过孔与尽可能短的走线)。因为在此给出一个模块优先级以供设计人员参考,从而提高方案设计的效率,增加一版work的可行性。将优先级以阿拉伯数据排列
