2.2 1000M Ethernet Interface
As Freescale i.MX6Q has integrated Gigabit Ethernet MAC internally, you just need to connect the PHY chip externally when
using. This platform’s Ethernet transceiver uses RTL8211E as Ethernet chip. Currently, it works in Gigabit mode, the card
crystal is 25M. Mode can be configured through the resistor R87~R95 (please refer to the Base Board Diagram and RTL8211
Chip Manual for detailed configuration). The development board is configured as Gigabit full-duplex mode by default.
The RTL8211E/RTL8211EG is Realtek’s newest network PHY chip, supporting 10Base-T/100Base-TX/1000Base-T, IEEE
802.3 standards. The interface of the main chip MAC is RGMII, which supports Crossover, Detection, Auto-Correction,
polarity correction, adaptive equalization, cross-talk, cancellation, echo cancellation and other functions. The platform uses
RTL8211E as the network card, it is because RTL8211EG’s package is QFN64, RTL8211E’s package is QFN48, but the price is
so different between the two, RTL8211E is cheaper, while RTL8211EG is a little expensive, the main difference is RTL8211EG
supports GMII/MII interface, RTL8211E doesn’t. So if you are consider more about the cost control, it is suggested to chose

RTL8211E, RTL8211EG’s price is more expensive than RTL8211E by 60~70%.Specially,need to use GMII/MII interface,
please use RTL8211EG.
This platform Ethernet interface integrates transformer, after connecting the network cable and configuring correctly, you can
surf the Internet. The interface is as below:
2.3 Double-deck USB Interface
The 4-channel USB HOST interface is extended by USB-HUB chip FE1.1S. It is the USB2.0 HUB chip with high performance,
low power and cost-effective, it can extend 4-channel HOST output and support hot plug. Through one USB double-deck
interface--USB1 and the extended interface—J6, it can extend to 2-channel HOST. It supports external connection of
USB-WIFI module, USB Bluetooth module, USB mouse & keyboard, U disk and other USB equipment.

2.4 I2S Audio Input/output Interface
I2S Audio Circuit adopts Wolfson Microelectronics audio converter chip--WM8960, which is a low power, high quality stereo
coder-decoder, especially designed for portable digital audio applications.
WM8960 integrates a complete microphone interface and a stereo headphone driver, as there is no need separate microphone,
speaker or headphone amplifiers, which greatly reduces the external component requirements. The advanced digital signal
processing realizes the automatic level control of microphone or circuit input.
The stereo uses 24-bit sigma-delta analog digital converter (ADC) and digital analog converter (DAC), while using a low power
oversampling digital interpolation and decimation filters, as well as a flexible digital audio interface. Master clock can be input
directly or generated by the built-in internal phase-locked loop, which supports the most common clock mode.
WM8960 operates at analogue supply voltages as low as 2.7V. To save power, the digital core can operate at voltages down to
1.7V. The speaker supplies voltage 5.5V superlatively, and each channel’s output can be 1W8Ω load, other power voltage is up
to 3.6V. Different parts of the chip can be turned off by software control. Using 5*5mm 32pins QFN package, it’s ideal for
making handheld and portable devices.

2.6 Switch Interface
J5 is the reserved power switch interface, using 2.54mm pitch white interface, and you need to let the external switch leads
docking when using. Its function is to skip the power management circuit and control the board’s power on or off directly.
If you use the J5 as the power switch, it may cause the situation that it can’t be switch off after power on. This is because the
application has the software power off. In this case, you need to modify the application to cancel the software control or remove
the MOS N1 on the circuit.
2.7 ON/OFF KEY
K1 is the power switch for the board. It is able to power on or off when pressing in long time (3-5 seconds), and wake-up
when pressing in short time (1 second).
