EZ-USB™ SX3 HDMI 4K capture kit system design
This section provides details of the CY-SD4210 EZ-
USB™ SX3 HDMI 4K capture kit design. The kit is bus
-powered
and supports a SuperSpeed USB-C cable to connect to the PC. To demonstrate the full functionality of the kit,
an HDMI source must be connected to the onboard HDMI connector.
3.1
Top-level hardware design
The CY-SD4210 EZ-
USB™ SX3 HDMI 4K capture kit consists of the SX3 device, the ECP5 FPGA from Lattice
Semiconductor, an HDMI receiver, an external SPI flash module, the DDR3 SDRAM, onboard regulators, and
USB-C and HDMI connectors.

3.2
CY-SD4210 design details
The CY-SD4210 board consists of the SX3 silicon (CYUSB3017-BZXI), SuperSpeed MUX, 64-Mbit SPI flash, HDMI
receiver, ECP5 FPGA and DDR3 SDRAM. The board is bus-powered and uses a 19.2 MHz crystal for operation.
The kit provides HDMI and USB-C interface connectors to connect an external HDMI source and PC,
respectively.
3.2.1
USB connector (J1)
A certified USB-C receptacle (J1) onboard allows SX3 to communicate with the PC via a SuperSpeed USB-C
cable that is provided with the kit. Use this port to test SX3 applications. Using the Type-C interface allows
access to the SX3 debug interface using serial terminal messages.
3.2.2
Switch (SW1)
Mode selection switch, SW1:
Selects the mode in which SX3 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 SX3 to boot from the onboard SPI flash.
