1. Introduction
The ML4019-MCB is designed to provide an efficient and easy method of programming and
testing 56G DSFP transceivers and active optical cables. It includes a complete user-friendly GUI
supporting all features defined by DSFP MSA and simplifying configuration processes to enable
intuitive memory map programming and testing. It is designed to simulate an ideal
environment for DSFP transceivers module testing, characterization and manufacturing.
2. Key Features
supports two lanes that operate up to 28 Gbps each
Matched differential traces length
High performance signal integrity traces from K-connectors to DSFP host connector
I2C master driven from both on board microcontroller or external pin headers
On-board pin headers for MSA low speed signals external control
Current Sense
Voltage Sense
Temperature Sense
USB interface
3. ML4019-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 ML4019-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 (J4) that should be connected to 5V AND 3.3V
taking into account pins distribution, where jumper U9 must be populated
Using the banana plugs (U13) that should be connected to 3.3V where jumper U8
must be populated
Connect the host to your PC using a Type-B mini to Type-A USB cable.

3.3 LED Indicators
The ML4019-MCB includes on-board LEDs, for quick debugging and monitoring purposes. LEDs
are summarized below:
LED D1 indicates whether a USB cable is plugged or not.
LEDs D2 and D5, colored green and red, respectively, are used for diagnostic purposes:
If D2 is on: USB is locked and device is recognized by the USB driver
If D5 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
3.4 Low Speed Signals
3.4.1 External I2C
The I2C bus can be accessed externally using U7 pins. In this case a jumper should be
placed on pin header P1 (HW_I2C) shown in the image below.

3.4.2 External HW Control
Also Low Speed Signals are controllable using an external source, this could be done
through J6 (H_LPWN pin) and J7 (H_RSTN Pin) pin headers. In this case a jumper should be
placed on pin header J1 (HW_CTRL) shown in the image below.
When the jumper is inserted on J1, the output signals are tri-stated from the
microcontroller, and hence could be controlled from the external source.
Figure 2: External Control Signals
The low speed signals circuit shown below shows the connection of these signals to the
microcontroller and DSFP connector.

4. ML4019-MCB Software
The ML4019-MCB is accessible and controlled through application software. This software is
MSA compliant and provides a user-friendly interface to operate the board and access all
features. The communication between the ML4019-MCB board and the software is established
through USB connection.

7. Bootloader
Accessing in bootloader mode allows the user to reprogram the microcontroller, this is done as
described below:
1. Connect a jumper on (J2) situated close to the microcontroller.
2. Connect a USB cable between the PC and Board.
3. Power up the board with a +3.3V supply.
4. LEDs (D2, D5) start blinking.
5. Remove jumper.
6. Open the software “Microchip USB HID Bootloader v2.3”.
7. Click on “Open Hex File”.
8. Choose the new FW to download.
9. Click on “Program/Verify”.
10. Once the software finishes programming press on “Reset Device”.
11. After reset the Firmware is successfully updated.
