multiLane ML4064-MCB-112 Host Test Board Owner’s Manual
Introduction
The ML4064-MCB-112 is designed to provide an efficient and easy method of programming and testing 800G 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.
Key Features
- Supports 8x112G interfaces
- I2C master driven from both on board microcontroller or external pin headers
- 4mm or 1.85mm Connectors
- Current Sense
- Matched differential trace length across all channels
- High performance signal integrity traces from K connectors to OSFP host
- On-board pin headers for MSA input control signals
- User friendly GUI for I2C R/W commands and loading custom MSA memory maps
- Four corner testing capability
- USB interface
Ordering options
| Option | Part Number | Description |
| #1 – IHS | ML4064-MCB-112 | OSFP MCB with regular OSFP IHS cage |
| #2 – RHS | ML4064-MCB-112-RHS | OSFP MCB with OSFP RHS cage |
ML4064-MCB-112 Hardware
The subsequent sections cover the essential parts in the hardware, for board operation and testing.
Power-Up
To power up the ML4064-MCB-112 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 U2 must be populated
- Using the banana plug (U8) that should be connected to 3V where jumper U1 must be populated
- Connect the host to your PC using a Type-B mini to Type-A USB cabl
Operating Conditions
According to the powering method described in section 3.1, the input voltage supply must follow the table below.
| Parameter | Symbol | Condition | Min | Typical | Max | Unit |
| +5 | P5V | Supply from J2 (P5V pin) | – | 5 | – |
V |
| +3.3 | P3V3 | Supply from J2 (P3V3 Pin)
OR banana plug U8 |
3.0 | 3.3 | 3.6 |

LED Indicators
The ML4064-MCB-112 includes on-board LEDs, for quick debugging and monitoring purposes. LEDs are summarized below:
- LED D11 indicates whether a USB cable is plugged or
- LEDs D13 and D12, colored green and red, respectively, are used for diagnostic purposes:
- If D13 is on: USB is locked and device is recognized by the USB driver
- If D12 is on: USB is not connected or USB driver is not found
- If both are off: board is not powered correctly or firmware is corrupted
- If both are blinking: the board is in Bootloader mode
Low Speed Signals
External I2C
The I2C bus can be accessed externally using U156 pins. In this case a jumper should be placed on pin header P16 (HW_I2C) shown in the image below.
External HW Control
Also Low Speed Signals are controllable using an external source, this can be done through J4 pin header. In this case a jumper should be placed on pin header J3 (HW_CTRL) shown in the image below.
The low speed signals circuit shown below shows the connection of these signals to the microcontroller and OSFP connector.
ML4064-MCB-112 Software
