5 Mechanical Specifications
6 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.
6.1 Power
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 ¡Ü50mV at idle state and ¡Ü100mV at full load.
6.2 Ethernet Port
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.
6.3 Ethernet Port
There are 2 RGMII(1000M) Ethernet port available form the Core moudle.Plz Follow the reference Design.
6.4 USB
USB 2.0 interface are available, customer can configure them to host or host/device by change the software configuration. Careful layou include equal length, appropriate space and 90ohm differential resistor for the differential USB signal is necessary.
ESD protection can be reserved.
6.5 UART Port
There are two UART port One is UART Lite £¬The other one is UART Full£¬Both
can be used as the serial port for system debug or used as communication with Zigbee For attention, the external UART chip like RS232 is necessary when using the port.
The connector on your main board can be usb,DB9,and any other kinds. Pull up to 3.3V on the RXD is
necessary.
6.6 I2C
One I2C port can be use. External pull up to 3.3V is necessary.
6.7 PCM
The PCM Pin be share with UARTF/I2S£¬detailed Info Plz refer Datasheet.
6.8 PCIE
One PCIE interface £¬Can be used as expand the PCIE wifi card(802.11a/802.11ac)and
storage.
6.9 GPIO
The Core Module Supply One Standard GPIO(GPIO0)£¬But almost 45 GPIO be used with UART Full,RGMII,I2C,ETH,at all¡£If these Pin is free£¬you can change it to GPIO mode£¬ Plz Follow MT7620A Datasheet.
6.10 Antenna Connecter
The RF switch coaxial connector on the Core Moudle is I-PEX: 20279-001E-01.If
the RF connected to the customer¡¯s main boad, the RF match circuit and suitable trace should be noted.
