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.

4 Stereo DAC with headphone amplifier

A CS43L21 stereo DAC with integrated headphone amplifier is used to generateaudio output on a 3.5mm audio jack. The CS43L21 is connected to the xCORE-200through an I2S interface and is configured using an I2C interface.

5 MEMS Microphones

The IM69D130 MEMS microphones used in this evalution board have a bottom portand measure 4mmx3mmx1.2mm, suitable for voice interface applications.

One microphone is placed at the center of the board (MIC_0). The remaining sixmicrophones are distributed equidistant around the board edge.

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.

8 Expansion Header

The board has an expansion header containing 7 general purpose IOs, controlledby the xCORE-200, and an audio MCLK.

By removing R67 and inserting a 0R link into R17, the expansion header audioMCLK can be used as an alternative to the CS2100-CP (CirrusLogic) Fractional-NPLL (U22) output.

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.

J1

Figure 14:

USBcomponents

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:
