1. Introduction
The ML4064-MCB is designed to provide an efficient and easy method of programming and
testing 400G OSFP transceivers and active optical cables. It includes a complete user-friendly
GUI supporting all features defined by OSFP MSA and simplifying configuration processes to
enable intuitive memory map programming and testing. It is designed to simulate an ideal
environment for OSFP transceivers module testing, characterization and manufacturing.

3. ML4064-MCB Hardware
The subsequent sections cover the essential parts in the hardware, for board operation and
testing.
3.1 Power-Up
To power up the ML4064-MCB host, steps are as follow:
•The host TOP is where the cage is mounted
•Two options are available to power up the board:
➢Using the four pins power connector (J2) that should be connected to 5V AND 3.3V
taking into account pins distribution, where jumper L15 must be populated
➢Using the banana plug (U8) that should be connected to 3.3V where jumper L16 must
be populated
•Connect the host to your PC using a Type-B mini to Type-A USB cable.
