400G PAM4 Active Module Performance Evaluation Test Board In QSFPDD Package

400G PAM4 Active Module Performance Evaluation Test Board In QSFPDD Package

The U9608 Test board is a test device with a variety of advanced functions. Here are some of the key features of the U9608 test board:

1.Package interface: It adopts QSFPDD package interface, especially suitable for QSFPDD 400G PAM4 optical module.
2.Baud rate support: The U9608 test board supports PAM4 baud rates ranging from 25GBd to 28GBd.
3.Electrical interface type: For the electrical interface of TX and RX, it uses a 40GHz 2x8 multi-coaxial connector and uses CML levels for input and output.
4.Current and voltage monitoring: The test board supports real-time current monitoring and overcurrent protection. In addition, it supports the pull test of the supply voltage, and the voltage range can be adjusted from 2.8V to 4.0V. This means that it can meet the minimum 3.0V and maximum 3.6V voltage pressure tests of module pull. At the same time, it also has a voltage real-time monitoring function, the default output is 3.3V, and the output voltage is adjusted in real time according to the current of the current module, to ensure that under different loads, the stable change range of the supply voltage is within 10mV.
5.Temperature adaptability: The U9608 test board supports applications at industrial-grade temperatures, demonstrating its excellent environmental adaptability.
6.MCU and communication: The MCU I2C rate on the test board is about 100KHz. The data is transferred to the EEPROM information of the I2C read/write module through the MCU. The communication mode uses USB HID, no driver is required, and I2C data can be directly read and written to the module and MCU through DLL API.
