Overview
The chip on the MT7620 router includes the 802.11n MAC and baseband, 2.4 GHz. The radio and FEM, a 580 MHz MIPS® 24K µCPU core, a 5-port 10/100 switch and two RGMIIMT7620s include everything you need to build an AP router from an AP. single chip microcomputer. The embedded high-performance CPU can handle advanced processing applications such as routing, security and VoIP effortlessly. The MT7620 also includes a choice of interfaces to support a variety of applications, such as
USB port for accessing external storage .
There are several high-performance, low-performance hosts (MIPS 24KEC, USB, PCI Express) on the MT7620 SoC.
Delay Rbus, (Ralink bus). In addition, MT7620 SoC supports low-speed peripherals such as UART, GPIO, SPI via low-speed peripheral bus (PBUS). The SDRAM/DDR1/DDR2 controller is the only bus from RBUS. It includes an advanced memory scheduler to arbitrate requests from bus masters, enhancing the performance of memory access-intensive tasks.
The MT7620 SoC includes a high-performance 580 MHz MIPS24KEC CPU core and a USB host controller/PHY, which is designed to enable a large number of high-performance, cost-effective IEEE802.11n applications with a MediaTek (Ralink) client card. Here are several MIPS 24KEC, USB, PCI Express high performance, low performance latency Rbus, (Ralink bus) on MT7620 SOC.

comment
1. MT7620A. The switching regulator and PMU circuits should be in the bottom right corner.
2. The Ethernet port should be in the lower left corner of the MT7620A.
3. DDR2 should be located on the left side of MT7620A.
4. The 3.3V to 1.8V LDO should be close to DDR2.
5. The RF circuit should be on the top of the MT7620A.

7. The RF circuit should be on the top of the MT7620A. The XTAL should be close to the MT7620 and the clock trace should have ground. Avoid interference around planes, but as far away from RF circuits as possible
