1 Introduction to schematic diagram and PCB layout module

2 Types and descriptions of schematic and PCB layout modules

3 How to use the PCB layout module  

1 Schematic and PCB layout module introduction:

1) What are schematics and PCB modules?

Make "validated" schematics and PCB layouts into specific designs that can be reused in future similar products

2) Advantages of schematics and PCB modules

Please design the circuit according to the schematic diagram provided by MTK, and keep the same screen name and MMD when importing MMD;

When the installation is complete and the layout is ready, please import the module, the relative position of BB and DDR should remain MMD.

3) Precautions for implementing PCB layout module

Main power capacitor placement, routing and vias (including GND vias)

(Main power rate: DVDD_GPU, DVDD_CORE, DVDD_MODEM, DVDD_MFG_SRAM, DVDD_TOP_SRAM, VSRAM_PROC_PMU, VDRAM_PMU, EMI_ VDD2, EMI_ VDDQ, DVDD_DVFS);
