General Description

The MAX96752 evaluation kit (EV kit) provides a proven design to evaluate the MAX96752 high-bandwidth Gigabit Multimedia Serial Link (GMSL) deserializer with spread spectrum and full-duplex control channel with the use of a standard FAKRA coaxial cable or HSD STQ cable. The EV kit also includes Windows® 10 application software to provide a simple graphical user interface (GUI) for exer-cising features of the device.
For complete GMSL evaluation, order the MAX96752 coax EV kit with a companion GMSL-2 serializer board (MAX96751 coax EV kit, see note in Ordering Information).
Note: In the following sections, deserializer means MAX96752 and serializer means MAX96751.
Note: This document applies to both coax and HSD-STQ evaluation kits, coax EV kit is referenced in this document.

Procedure
The MAX96752 COAX/STQ EV Kit is shipped with the PCB fully assembled and tested. Follow the steps below to verify board operation:

1. Download and install the latest GMSL public GUI from Analog.com
2. Verify that the on-board jumpers on the deserializer board are in their default positions (Figure 3) with SW1 off.
3. Configure SW2 as shown in Figure 3 to set deserializer address to 0x90, COAX mode, and I2C control.
4. Connect the FAKRA cable from the OUTA+ terminal on the serializer board to the INA+ terminal on the deserializer.
5. Connect the +12V wall DC power supply to J1. See Figure 4 for power supply details.
6. Turn SW1 on for both the serializer and deserializer EV kits.
7. Verify that the blue power LED and red Teensy® LED are illuminated.
8. Verify the LOCK LED on both serializer and deserializer EV kits light up, indicating that the link has been successfully established. If the LOCK_LED is off or ERRB LED is illuminated on the deserializer board, see the Troubleshooting section. Due to the default error conditions enabled on the serializer device versus the default hardware configuration of the serializer board, the ERRB LED is illuminated upon power-up.
9. Connect the USB cable between the PC and J4 on the serializer EV kit. Start the GUI by selecting Start | Programs | Maxim Integrated | MAXSerDesEV-GMSL.
10. When the GUI opens, it automatically searches for any active listener in both I2C and UART mode and identifies a valid GMSL product. Once the serializer and deserializer are identified, they are shown as tabs in the GUI.
11. Read register 0x00 in both deserializer and serializer to ensure both devices are active.
12. The basic bring-up is now complete. Refer to Help | User’s Manual for GUI operation, GMSL2 User’s Guide for configuration of this device and its available features, or Maxim Applications for additional details and support.

Troubleshooting
If the MAX96752 EV kit fails to power up or does not function properly, try the appropriate remedial actions below:

1. Make sure the boards’ red power switches (SW1) are set to the ON position.
2. Verify that the device is powered properly. Check to ensure that the voltages at all device pins are within their operating ranges.
3. Check that all jumpers are correctly set. See the default jumper settings table in the serializer and deserializer EV kit data sheets. Also, ensure that all jumpers are firmly attached. Replace loose or damaged jumpers if necessary.
4. Check that the USB cable is properly seated in the USB port. The USB LED should be lit if connected to a PC, even if the board is powered down.
5. Check that the serializer and deserializer GMSL generations match. Both devices should start in the same mode (GMSL2).
6. Check that the COAX/STQ cable connection between the serializer and deserializer is good–it clicks when plugged in fully.
7. Check to see if the DUT has been inadvertently put into Teensy reset mode. The board’s TEENSY_RST button should only be pressed when firmware is being flashed to the DUT. If the button is pressed during normal operation, the device goes into Teensy reset mode. Power-cycle the board to resume normal operation with the current firmware.
8. Check that the I2C/UART jumpers match the DUT communication mode (SCL/SDA for I2C, TX/RX for UART).
9. Check that the AC coupling capacitors are populated correctly and route the serial link to the correct connector for COAX or STQ mode. For coax boards, capacitors C54 and C57 (SIOA) and capacitors C46 and C56 (SIOB) should be populated. For HSD boards, capacitors C60 and C61 (SIOA) and capacitors C58 and C59 (SIOB) should be populated.(MAX96752 COAX/HSD EV kit boards are shipped with the correct capacitors installed.)
10. Check if the LOCK LED is ON in the absence of a connection to the deserializer: If so, then the DUT is either not powered correctly or damaged.
11. Check that the microcontroller firmware is active by observing the blinking red Teensy LED (DS5) at power-up. If the LED is not blinking, refer to the available software documentation to reprogram the microcontroller.
12. Check that the PC is detecting the COM port when the micro-USB cable is connected. Use the Windows Device Manager to check the COM port status.
13. Power-cycle the board and reopen the GUI.
14. If the serializer board is faulty, try a new or different serializer board.
