videos from the block cameras directly into the PC. This user guide describes the steps to install the software
required by the kit and to operate the development board provided with the kit.
This kit is intended to be a solution demo kit for UVC and U3V video streaming applications from the block
camera to a PC via the USB-C interface.
See the device datasheets [3] to understand and compare the various features supported by EZ-USB™FX3
controllers.
This kit supports the following key features:
•UVC and U3V video streaming up to 1080p (FHD) at 60 fps from off-the-shelf BT.1120 and LVDS block cameras
•USB bus-powered operation
For FX3 controller details, see the webpage.

3System design
This kit is bus-powered. To demonstrate the full functionality of the kit, connect the block/bt.1120 camera
module to the onboard Low Voltage Differential Signaling (LVDS) or FFC connectors respectively.
3.1 Top-level hardware design
Figure 2 FX3 LVDS camera kit architecture
3.2 DEMO_FX3_LVDS_CAM01 design details
The DEMO_FX3_LVDS_CAM01 board consists of the FX3 silicon (CYUSB3014-BZXI), USB 5 Gbps MUX, 64-Mbit SPI
flash, ECP5 FPGA and DDR3 SDRAM, and power supplies. The kit is bus-powered and uses a 19.2-MHz crystal for
operation. The kit has an FPC interface to connect to the BT.1120 block camera module provided with the kit.
An LVDS block camera can also be connected to this kit via the micro coaxial connector available on the board.
Apart from these interfaces, the kit has a USB-C interface to connect to PC.
3.2.1 USB connector (J1)
An onboard certified USB-C receptacle (J1) allows FX3 to communicate with the PC via a USB-C 5 Gbps cable
provided with the kit. Using the Type-C interface allows access to the FX3 debug interface using serial terminal
messages.
3.2.2 Mode selection switch (SW1)
This switch selects the mode in which FX3 must boot upon power-on. The kit can boot in two modes based on
the position of this switch.

To program the device, set SW1 in USB mode. After programming, setting the mode switch in SPI mode and
rebooting the device by power cycle allows FX3 to boot from the onboard SPI flash.

3.2.3 Power supply
The kit consists of five DC-DC buck and one DC-DC boost regulators with ratings as listed below. AP3428KTTR-
G1 and PAM2423AECADJR from Diodes Inc. are used due to their small form factor. All voltages listed below are
generated from VBUS (i.e., 5 V ± 0.25 V).
•U1: 3.3 V ±5% at 1 A
•U2: 2.5 V ± 5% at 1 A
•U3: 1.5 V ± 5% at 1 A
•U4: 1.2 V ± 5% at 1 A
•U8: 1.1 V ± 5% at 1 A
•U16: 9V ± 5% at 5.5 A
The kit also uses a 2 A DDR termination controller (U9) to power the VTT bus terminations. It also provides the
reference output to the DDR IC.
3.2.4 EZ-USB™ FX3 (U6)
This is a USB 3.1 Gen 1 5 Gbps controller with a 32-bit ARM926EJ core CPU and 512-KB embedded SRAM. It
supports UVC, UAC, U3V, and USB Vendor Class protocols. With a general programmable interface (GPIF II) of 8-,
16-, 24-, and 32-bit data bus at 100 MHz, FX3 supports slave FIFO and parallel camera interface features. It has
dedicated interfaces for SPI flash and I2C. FX3 supports selectable clock input frequencies at 19.2, 26, 38.4, and
52 MHz. Additionally, a dedicated 19.2-MHz crystal input support is also available. It has a 121-ball, 10- × 10-
mm, 0.8-mm pitch, Pb-free ball grid array (BGA) package.
3.2.5 SPI flash (U11)
The kit firmware is stored on an Infineon 64-Mbit SPI flash. After power-on, FX3 fetches the required details
from the firmware image, stores it in its RAM, and starts executing from it.
3.2.6 LVDS camera coaxial connector (J6)
The kit has an onboard 30-pin micro-coaxial connector to connect the LVDS block cameras.
3.2.7 FPC connector (J7)
The kit has an onboard 30-pin FPC connector to connect the BT.1120 block camera provided with the kit.
3.2.8 Crystal (Y1, Y2)
Y1 is a 19.2-MHz crystal used by FX3 to generate the clock for its operation.
Y2 is a 100-MHz crystal used by FPGA to generate the clock for its operation.
3.2.9 LED (LED1, LED2)
LED1 (user LED) is a green LED connected to GPIO_4 of FX3. It is an application / firmware-controlled LED.
LED2 (PWR ON) is a green LED with power on; this LED glows green, indicating the power to the LVDS camera
board is available.

System design
3.2.10 Lattice ECP5 FPGA (U10)
The kit uses an ECP5 family FPGA from Lattice Semiconductor. It is a high-performance device with dedicated
DDR3 RAM interfaces and supports high-speed signaling. This FPGA acts as a bridge between the block camera
and the FX3 device.
This FPGA is a 381-ball BGA package with 197 I/Os, having 0.8-mm pitch and a dimension of 17mm x 17mm.
3.2.11 DDR3 RAM (U12)
This kit uses MT41K128M16JT-125 IT:K TR from Micron. It is a 2Gb 1600MT/s DDR3 SDRAM used by the FPGA as a
frame buffer to process the digital video data received from block camera. It operates at VDD = VDDQ = 1.5V
±0.075V
As with standard DDR SDRAM, the pipelined, multibank architecture of DDR3 SDRAM allows for concurrent
operation, thereby providing high bandwidth by hiding row pre-charge and activation time.
The DDR3 RAM is an industrial grade 96-FBGA package.

5.7 Changing camera parameters in LVDS block camera
Note: This kit supports modification of camera parameters only in the UVC streaming mode. However, it is also
possible to implement this feature in the U3V mode.
To change the camera parameters, the VISCA serial commands are sent over USB CDC class.
The following are the prerequisites for changing the camera parameters:
1. Download and install TeraTerm
2. Download and install any VISCA serial control software such as FCB Control software V5102.exe.
After streaming the UVC video from the LVDS camera as described in section 5.5, open the device manager and
confirm the following:
•FX3 CAMERA appears in the Camera group
•Two COM ports appear in the Ports (COM&LPT) group. One COM port is used to debug prints and the other is
used to control the camera using any VISCA serial control software. Find the COM port used to debug prints
by opening TeraTerm with the selected COM port.
Note: The FCB Control software allows a COM port number of up to 16. Re-assign the COM port number to within
16 if the PC assigns a port number greater than 16 by following the steps given in section 6.3.
Open FCB Control Software V5102.exe and choose the appropriate COM port and click OK.
Figure 21 Selecting COM port in Sony FCB Control Software application
The application opens as shown in the following screenshot. It may throw up an error saying the FCB Control
Software has stopped working. Ignore the warning and continue with controlling the camera with the provided
feature.
