MAX96717 DPHY Evaluation Kit

General Description

The MAX96717 DPHY evaluation kit (EV kit) provides a proven design to evaluate the MAX96717 high-bandwidth gigabit multimedia serial link (GMSL) serializer. It supports spread spectrum and full-duplex control channel communication using a standard FAKRA coaxial (Coax) or HMTD cable. The EV kit includes software for Windows® 7 and Windows® 10, featuring a simple graphical user interface (GUI) for exercising the device's features. The EV kit comes with a MAX96717, MAX96717F, or MAX96717R IC installed.

For complete GMSL evaluation using a standard FAKRA coaxial cable or HMTD cable, the MAX96717 Coax EV kit and a companion deserializer board (MAX96716 Coax EV kit) are recommended.

In this document, "serializer" refers to the camera serializer interface (CSI) serializer, including MAX96717, MAX96717F, and MAX96717R. "Deserializer" refers to the CSI deserializer MAX96716 and its variants. This document applies to both Coax and HMTD evaluation kits.

Benefits and Features

• Ability for Serializer to Send GMSL Data to Deserializer, Converting it into MIPI CSI-2
• Windows 10 or Higher Compatible Software Support
• USB Controlled Interface (Cable Included)
• Powerful and Simple GUI for Comprehensive Device Feature Evaluation
• Board Powered by USB, 12V Wall Adapter, or External Power Supply
• Proven PCB Layout
• Fully Assembled and Tested

Note: Coax EV kits are configured to use PoC and FAKRA connectors. For HMTD connectors, order HMTD-specific EV kits.

Block Diagram

Figure 1 illustrates the MAX96717 DPHY EV Kit Block Diagram. It shows the MAX96717 serializer connected to a Teensy MCU, level shifters, power management ICs, and various connectors (FAKRA Coax, HMTD, USB). The system is powered by USB, a 12V adapter, or an external supply, and includes line fault monitors and power test points.

Board Layout

Figures 2, 3, and 4 provide views of the MAX96717 EV Kit board, including the top view, bottom view, and default jumper configurations. Figures 17, 18, and 19 show detailed PCB layout views for various layers (Silk Top, Top, Layer 2, Layer 3, Layer 4, Layer 5, Layer 6, Layer 7, Bottom, Silk Bottom).

Quick Start

This procedure applies to both Coax and HMTD EV kits. Figure 5 shows a typical application using the CSI serializer with a CSI deserializer.

Required Equipment

• MAX96716 DPHY EV kit rev A
• FAKRA Cable Assembly
• PC with Windows 10 or higher and GMSL2 Software
• PC running GMSL Software
• Power supply source (500mA USB port, 5V/1A DC Supply or 12V barrel jack DC supply [provided])
• Micro-USB cable

Procedure

1. Follow the steps below to verify board operation.
2. Download and install the latest GMSL EV kit software from www.analog.com or contact Analog Devices Applications. Follow the GMSL GUI User's Guide instructions.
3. Verify that jumpers on the serializer board are in their default positions (as shown in Figure 2), and SW1 is in the OFF position.
4. Verify that jumpers on the deserializer board are in their default positions, and SW1 is in the OFF position.
5. Set up the system: Connect FAKRA cable from the serializer to the deserializer (Link A or Link B). Connect a +12V wall power supply into the POWER connector.
6. Turn SW1 to the ON position on both serializer and deserializer EV kits.
7. Verify that all power LEDs and the red Teensy LED are illuminated, indicating the board is powered and the Teensy uC is active.
8. Verify the LOCK LED on both serializer and deserializer EV kits are illuminated, indicating a successful link establishment. If LOCK_LED is OFF or ERR_LED is ON, refer to the Troubleshooting section.
9. Start the GMSL GUI software.
10. When the GUI opens, it searches for active listeners in I2C and UART modes and identifies a valid GMSL product. Serializer and deserializer are shown as tabs.
11. Read register 0x00 in both deserializer and serializer to ensure both devices are active.
12. Basic bring-up is complete. Refer to the GMSL GUI User's Guide, GMSL Bring-up Guide, the latest datasheet, or contact Analog Devices Applications for more details.

Configuration (CFG) Pin Settings

The serializer's CFG pins use the pin voltage latched at power-up for configuration. On-board I2C-configurable digital potentiometers or 0402 resistors set these voltage levels. By default, the board uses digital potentiometers.

CFG states can be configured using the GMSL 2 GUI via Tools > Set CFG Pin Levels. To switch between digital potentiometers or resistor networks, use 0Ω resistors to connect the CFG0/1 nets. CFG pin voltages can be monitored on CFG0 and CFG1 test points or the 2x12 MFP header (J1).

If the serializer is not identified in the GUI, CFG pins can still be written to. Refer to the Troubleshooting section for more information.

Voltage levels scale with VDDIO. Tables 1-5 provide voltage levels necessary for serializer configuration in different modes.

CFG Pin Input Maps

Tables 1-5 detail the mapping of CFG pin input voltage (as a percentage of VDDIO) to suggested resistor values, I2CSEL, ROR/XTAL, Device Address, CXTP, Data Rate (Gbps), and Tunnel/Pixel Mode for MAX96717, MAX96717F, MAX96717R variants.

Serializer Jumper Descriptions

Table 6 details the connectors, jumpers, and test points on the EV kit. Power configuration can be altered for external supply connections. Figure 6 shows power connection options.

Troubleshooting

If the MAX96717 EV kit PCB fails to power-up or function properly, consider the following remedial actions:

1. Verify the board's power switch (SW1) is ON.
2. Ensure proper device power by checking voltages at device pins and power LEDs.
3. Check jumper settings against default configurations in serializer/deserializer EV kit datasheets and ensure they are firmly attached.
4. Verify the USB cable is securely seated.
5. Confirm the coax/STP cable connection between serializer and deserializer is secure.
6. Ensure the DUT is not in Teensy reset mode (TEENSY_RST button is for firmware flashing only). Power cycle the board if it is.
7. Validate correct CFG pin voltages for serializer configuration, checking biasing at power-up.
8. If the device is not identified in the GUI due to incorrect CFG settings, reconfigure them via the GUI (Options tab > Identify Devices). Monitor low-level Commands tab for I2C write success.
9. Check I2C/UART jumpers match the DUT communication mode (SCL/SDA for I2C, TX/RX for UART).
10. Verify AC coupling capacitors are correctly populated and the serial link routing is appropriate for Coax or STP mode.
11. Check microcontroller firmware activity by observing the blinking red Teensy LED at power-up. Refer to software documentation if it's not blinking.
12. Confirm the PC detects the COM port via the micro-USB cable using Windows Device Manager.
13. Power-cycle the board and reopen the GUI.
14. Try a different serializer or deserializer board.
