Purpose and scope This user guide provides set up instructions and the description of the STDP2650 reference board targeted for DP to HDMI conversion applications. B0642-GUD-01 MegaChips’ Proprietary Information – Strictly Confidential Page 4 of 12 RD3-2650 2. Description The STDP2650 is MegaChips’ latest generation DisplayPort converter series product that features a DisplayPort1.2 compliant receiver and an HDMI1.4 compliant transmitter, capable of handling high resolution video up to 4K2K 30Hz / FHD120Hz and audio up to 7.1CH. The STDP2650 RD3 board is intended for the product evaluation and testing. The board contains a standard DP input connector, a standard HDMI output connector, and a micro USB connector for powering. It also includes an SPI flash for storing the firmware, a UART connector for debugging and in-system programming purpose (firmware download), and an I2C slave interface to configure the device from an external host controller (optional). 2.1. Board picture Figure 1. Board picture 2.2. Set up instructions The picture below is a typical connection diagram showing a notebook with DisplayPort output driving a TV/monitor using an STDP2650 RD board. 1. Connect the DP output from the notebook to the DP input of the STDP2650 RD board using a standard DP cable. B0642-GUD-01 MegaChips’ Proprietary Information – Strictly Confidential Page 5 of 12 RD3-2650 2. Connect the HDMI output of the STDP2650 RD board to the HDMI input of the TV or the LCD monitor. 3. Power up the RD board by plugging in the micro USB cable (supplied with board) from an external USB source (ex: one of the USB ports from the notebook). 4. Use an HDMI TV or monitor that has audio output for testing the audio conversion through the STDP2650 RD board as well. 5. Once the connection is established and the board is powered, an image should appear on the screen within 2-3 seconds. Figure 2. Connection set up 2.3. Diagnosis If the image does not come up, follow the steps below for diagnosis. Note: The diagnosis requires MegaChips GProbe software and hardware tool. Contact MegaChips for the GProbe software and board. 1. Install the GProbe diagnostic tool on a Windows OS based PC/NB and set the baud rate to 115,200. 2. Connect the GProbe board to the serial port (or USB port if using the USB version of the GProbe board) of the computer. 3. Connect the other end of the GProbe board to the UART connector (CN502) on the STDP2650 RD board using 4-wire cable (part of the GProbe board). Note: Check the polarity while connecting the cable; Pin 1 is marked on the board. The 4-wire cable connection from CN502 to the GProbe board is 1 to 1. 4. Hit the reset button on the board (RESET SW501). You will see the firmware version and the date of the firmware in the GProbe window. This indicates that the DP Receiver IC is functional. If the message does not appear, reprogram the SPI Flash using the ISP method described in the GProbe user guide. B0642-GUD-01 MegaChips’ Proprietary Information – Strictly Confidential Page 6 of 12 RD3-2650 5. Using an oscilloscope, check the video input and output from the STDP2650 RD board. Note: Refer to the STDP2650 datasheet for pin-out descriptions. 2.3.1. In-System Programming (ISP) The STDP2650 RD board uses SPI Flash to store the firmware. For new firmware upgrade, following method is recommended. ISP through UART connector: Allows programming of the SPI Flash through the UART (CN502) connector. This requires GProbe board and GProbe software tool from MegaChips. Also contact MegaChips for the latest binary file. 3. RD3-2650 board description 3.1. Connection diagram Figure 3. Connection diagram 3.2. Principal components and functions Below is a summary of all necessary connectors, switches, and other components. Please refer to the latest board schematics for further details. B0642-GUD-01 MegaChips’ Proprietary Information – Strictly Confidential Page 7 of 12 RD3-2650 Table 1. Principal components and functions Label Description Ref des Power Input (+5 V, uUSB) Input 5 V, down conversion to 3.3 V, and 1.2 V. This board uses an LDO [low-dropout] for 3.3 V and 1.2 V. Note the analog and digital supplies (3.3 A and 3.3 D or 1.2 A and 1.2 D) are isolated using ferrite beads. CN301 STDP2650 MegaChips DP1.2 to HDMI1.4 converter IC U601 DP Input DP input connector CN401 HDMI Output DP output connector CN701 SPI Flash The board includes an SPI Flash of 4 MB to hold the firmware. The SPI Flash can be programmed (ISP) through UART interface. U502 S/PDIF Output Not populated Single wire S/PDIF output signal. Can route the encoded audio through SPDIF audio port CN503 Not Populated Host Interface (I2C) Host Interface (I2C): This is a provision to access the STDP2650 device from an external host controller through the Host Interface (I2C port) connection. CN501 UART (GProbe) GProbe Interface (+3.3 V logic): GProbe connector that connects to the STDP2650 UART port for communication with external PC sources for debug purposes. The MegaChips GProbe tool (software) and PC interface board together create a debug environment for device debug and firmware update. The GProbe interface is also used for ISP purposes. CN502 Reset The reset button, when pressed, triggers a system reset through the internal reset circuitry. The reset button is used for system reset and debugs purposes SW501 LED Single LED for indicating the power on status. D301 Crystal A crystal of 27 MHz. Y501 ESD Diodes ESD protection diodes for HDMI and DisplayPort signal (main lanes, AUX and HPD line). The board implements low cost ESD diodes. 3.3. Connector descriptions The STDP2650 RD board has the following connectors. The locations of these connectors are shown in the above board picture.
