This document describes the detailed Hardware specifications of Our WIFI Core Module.
This document designed for R&D department, Service Operator, System Operator, technical support, engineering servics.
Overview of Hardware Specification requirements:
Schematic Design Notes:
This part contains the schematic and PCB design notes for the customer who use the Core moudle for their own production. You can see our reference design and the MT7620A Spec for more detail design information.
There is only one external power 3.3VDC for the Core Moudle. Other powers as 1.8VDC,1.5VDC and 1.2VDC are all generated from the Core Moudle internally.Power consumption:
For the 3.3VDC,the main board should supply at least 1A current for the module, for security use ,the Margin should be 30% at least. Power Ripple: Small ripple is necessary for better performance, especially for the RF property. The 3.3VDC ripple should be ≤50mV at idle state and ≤100mV at full load.
There are 5 10/100M Ethernet port available form the Core moudle. For the MT7620A chip has already integrated the 10/100M Ethernet PHY, so the customer can only connect the ports to the Transformer directly. These Port are changed to Current type. As seen in the below.
