2 Introduction
The xCORE Microphone Array evaluation board is based on a two-tile xCORE-200XUF216-512-TQ128 device, which contains 16 32-bit logical processing cores thatdeliver up to 2000 MIPS compute and integrates 2MBytes Quad Serial PeripheralInterface (QSPI) flash.
For general information on xCORE-200 devices see the xCORE-200 ArchitectureOverview2. For device specific information on the XUF216-512-TQ128 devicesee XUF216-512-TQ128 Datasheet3.

3 Clock sources and distribution
The board includes three clock sources:
· xCORE-200 reference clock - 24MHz oscillator (Y1)
· Ethernet PHY reference clock - 25MHz crystal (X1)
· Low jitter clock source - 24.576MHz oscillator, used as reference clock to theCS2100-CP (CirrusLogic) Fractional-N PLL (U22).
The CS2100 generates a low-jitter output signal that is distributed to the xCORE-200 device (Tile1 & MCLK) and DAC (MIC-CLK). The CS2100 device is configuredusing the I2C interface.

6 Ethernet Connectivity
10/100 Mbps Ethernet connectivity consists of Microchip LAN8710A Ethernet PHY(U20) and an RJ45 connector (J3) with integrated magnetics. The PHY uses the25MHz crystal as a reference clock.

7 General purpose user interface
The board has 13 LEDs that are controlled by the xCORE-200 GPIO.
LED_0 - LED_11 (D2-D13) are positioned around the edge of the board, oneeach side of every microphone. LED_12 (D14) is positioned next to the middlemicrophone.
A green LED (PGOOD) by the USB connector indicates a 3V3 power good signal.
Four general purpose push-button switches are provided. When pressed, eachbutton creates a connection from the I/O to GND. To ensure correct behaviour, theport connected to the buttons (P4A) must always be defined as an input.

9 USB Port
The USB Micro-B receptacle (J1) is connected to the USB PHY integrated in theXUF216 device, and provides power for the on-board circuits, and USB interfaceconnectivity. Voltage tolerance should be as per USB VBUS specification values.
The power source is used to generate the following voltage rails:
· +1V0 (Core voltage to XMOS device)
· +2v5 (for headphone amplifier in DAC device)
· +3v3 for GPIOs and other accessory devices
Proper power-on sequence is indicated by power good LED (D1) in bottom side ofthe board.

NOTE: J1 must be connected at all times to provide power to the board.
NOTE: as this board is self-powered, the USB_VBUS pin on U5 is not connected.To ensure that the USB Audio 2.0 reference software operates correctly withthis board, please refer to the following design advisory:
