ATS2819/ATS2819P標準應用方案主要分為以下功能模塊: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原理圖設計總體原則1原理圖設計需要按照方案規格的要求實現各項硬件功能,盡量避免功能模塊相互間的資源沖突。如果存在I/O復用,接收復用等情況,除了需注意檢查I/O上電狀態,接口時序等,還需要注意復用的SIO工作頻率與工作電壓域是否符合要求(如WIO),確保功能設計正確實現。2原理圖設計要求性能達到要求。如穩定性,啟動電壓,功耗,ESD,EMI等。要注意檢查模塊電源開關狀態,選擇的原件標稱及精度、材質,接口保護元件和EMI濾波器等。3系統時鐘26MHZ,要求CL為7~9PF,精度為+-10PPM。這樣才能保證系統能正常工作。4當設計PCB受限于模具大小時,各個模塊無法保證均能得到最優的布局布線(如濾波電容要求靠近IC、走線上要求盡量少的過孔與盡可能短的走線)。因為在此給出一個模塊優先級以供設計人員參考,從而提高方案設計的效率,增加一版work的可行性。將優先級以阿拉伯數據排列
