M88 Evaluation Kit User Guide About this Document
1 About this Document
This document describes the use of the M88 Evaluation Kit. Its purpose is to help a user to set up the
board electrically and mechanically and how to communicate to it. It’s not a complete guide for all functionality provided by the M88 module it’s carrying. For this we refer to [1].
2 Scope
This document covers the M88 Evaluation Kit Rev A carrying the M80 Rev B module and running M88 v1.0.19 FW and later. It also covers the oscillator add-on board that is mounted on the M88 Evaluation Kit.
3 General Description
The M88 Evaluation Kit is an evaluation board for the M88 module. The board makes it possible to control and monitor all functionality provided by the M88. The board is powered through a single 5V power supply (included) or through Power-over-Ethernet. It provides two Ethernet interfaces for communication to the network, including PTP. It has a USB port for serial communication, SMA connectors and ITU-T G.703 V.11 compliant RJ45 for PPSIN, PPSOUT, TODIN and TODOUT plus multiple SMA connectors for configurable input and output frequencies. It provides a debug interface that can be used with Silicon Labs' Trace Adapter (not included) for communication with Silicon Labs' Developer IDE and a SPI interface for programming of the Si5348 chip onboard the M88. It also provides several jumpers for configuration.
The M88 Evaluation Kit also have two expansion slots intended for alternative oscillators and GNSS receivers respectively.

M88 Evaluation Kit User Guide Before you begin
4 Before you begin
You will need the following to use the board:
• Power supply 5V, 3A – included
• Ethernet cables (SFP and fiber if you intend to use optical communication) – not included
• SMA cables – not included
• USB cable – included
• GNSS antenna – not included
• A PC with a terminal program such as TeraTerm or PuTTy – not included
Optional devices in case you plan to write and debug your own SW for the M88 and/or configure the Si5348 of the M88.
• Silicon Labs' Trace Adapter
• Silicon Labs Developer IDE
• SiLabs Trace Adapter
5 Power
The board only needs a single 5V supply and depending on what add-on boards that are used (some OCXO can consume considerable amount of current when warming up) we recommend using a power supply that can deliver 3A.
The board can also be powered by a PoE switch if connected to Port 1. This will supply adequate power in most cases except for when a large OCXO is used on an add-on board. The M88 Evaluation Kit has onboard regulators to provide all necessary voltages for the components on the M88 Evaluation Kit including the M88. There is a green LED indicating 3.3V to the left of the board when seen from the front panel and another LED indicating if power is supplied by PoE.
6 Block diagram
The block diagram below shows the connections the M88 Evaluation Kit and to some extent, for improved understanding the connections on the M88 module itself. In the picture JS means jumper select. See section 10.

11 Add-on boards
11.1 Oscillator board
Silicon Labs provides optional oscillator board carrying a high-quality oscillator. To select the oscillator on the add-on board as reference source, move jumper P307 to pin 5-6. On the add-on board, allow for voltage control of the oscillator by moving the jumper P102 on the add-on board to pin 2-3.
Figure 11. Oscillator add-on board
If voltage control is used, DCO control needs to be turned off for DSPLL A and the voltage control range needs to be set for the mounted oscillator. This is done using the command ptp2 config -c 000 -v
<value> before the PTP engine is started.
Table 17. Oscillator voltage control range
11.1 GNSS board
Silicon Labs provides an optional GNSS board for satellite-based reference time. The board comes with an antenna connector cable.
Figure 12. GNSS add-on board
Plug the GNSS board into connector P504 and a patch antenna to the antenna connector cable. Make sure the antenna has a clear view of the sky.

M88 Evaluation Kit User Guide Connecting to the board
11.2 Enabling the GNSS LED
There is a LED situated close to P504 which can be used to indicate 3D fix on the GNSS receiver. To enable this function, the following commands needs to be given to the M88 (they can be put in the startup.ini for convenience).
out cf 0x80 (set PF7 as output)
out df 0xf3 (set PF7 to high)
This will result in the LED blinking green when the GNSS is acquiring a signal and change to fixed green when the GNSS receiver has a 3D fix.
11.3 Check GNSS reception on the M88
After starting the PTP engine (mode 1, 2 or 3) give the following commands to check the status.
ptp2 gps status (this will print GPS interface status)
ptp2 gps nmea (this will print satellite information)
12 Connecting to the board
• After powering the system, connect one end of the USB cable to the M88 Evaluation Kit and the
other end to your computer. After connecting to the PC, the “Found New Hardware Wizard”
will appear on the PC. Allow the wizard to install the USB driver automatically.
• Verify which communication port is assigned to the USB serial port by checking the Device Manager. You will need this information to configure the serial port being used.
• Open your terminal program application and connect it to the serial port using a baud rate of 115200, 8 bit data, no parity, 1 stop bit and no flow control.
• When you hit enter, you should see the following:
localhost.localdomain (M88-128, v1.0.x) Login:

13.2.2 Setting up the M88 Evaluation Kit
1. Connect Port 1 of the M88 Evaluation Kit to Port 1 of the Qg 2. Either directly or through a switch.
2. Either use DHCP or set an IP address and mask for the same subnet as the Qg 2 master.
ipconfig enet0 -a 192.168.2.101 -m 255.255.255.0
3. Make sure the M88 has a link (Port 1 refers to enet0 and Port 2 to enet1)
A:/root> ipconfig enet0 Interface "enet0": Ip address 192.168.2.101 Netmask 255.255.255.0 Gateway N/A MAC: fc:af:6a:02:52:15 Link state: 1000M/Full
Primary DNS N/A Secondary DNS N/A DNS timeout 10 Mailhost N/A
4. Verify the network connection by pinging the Qg 2.
A:/root> ping 192.168.2.100 Pinging 192.168.2.100 (192.168.2.100) Reply from 192.168.2.100: bytes=72, time<10ms Reply from 192.168.2.100: bytes=72, time<10ms Reply from 192.168.2.100: bytes=72, time<10ms Reply from 192.168.2.100: bytes=72, time<10ms
5. Start the PTP engine on the M88 Evaluation Kit in mode 0

7. Add the Qg 2 to the list of accepted masters
A:/root> ptp2 unicast 1 node add 192.168.2.100 0 0 0 A:/root> *** Unicast node dataset *** { Clock identity: FF:FF:FF:FF:FF:FF:FF:FF Network protocol: UDP/IPv4 Network address: 192.168.2.100 Node type: MASTER Announce granted: FALSE Announce interval: 1 Announce duration: 300 Sync granted: FALSE Sync interval: 0 Sync duration: 0 Delay response granted: FALSE Delay response interval: 0 Delay response duration: 0 Local priority: 0 }
8. Wait for the following message to appear
A new master time is received or the network topology was changed. Update local clock with new offset: sec: -0 nsec: 866271987
Please refer to [1] for commands on how to further control and monitor the PTP communication.
14 Using the PTP engine
Detailed information about how to interact with the PTP engine can be found in [1] which can be downloaded from our web site.
Any commands that the M88 should execute at startup, such as setting message rates etc. can be stored in the startup.ini file under the systems folder.
Using the serial port, the startup.ini file can be transferred to your PC using the kermit –s <filename> command, edited on your PC and then downloaded to the M88 again using kermit –r. If the terminal program in Developer is used, the commands send and recv can be used to transfer files instead of Kermit. Type help send respectively help recv for more information. Alternatively, FTP can be used over the network to upload the startup.ini file, edit the contents of the file, and then download to the systems folder.

M88 Evaluation Kit User Guide Using the PLL
15 Using the PLL
In the same way that the PTP engine can be configured using the ptp2 set of commands, there are many possibilities of configuring the onboard PLL functionality using the pll set of commands. Here’s a general description of these commands. For brief information of the various commands, type pll help in the console. For more detailed information, we refer to [1].
15.1 Configuration
Similar to the PTP engine, some parameters need to be configured in advance, in the sense that all modifications to the configuration are stored in memory and will only take effect after they are loaded into the PLL (see section 15.2). There are three sections that needs to be configured: Inputs, DSPLLs and Outputs. The currently loaded configuration can be shown using the command pll config print.
15.1.1 Configure inputs
Usage: pll config input <inpin_num> <command> [parameters]
Configure the input frequency for the specified input or disable/enable the specified input.
15.1.2 Configure DSPLL
Usage: pll config dspll <dspll_num> <command> [parameters]
Configure what input should feed the DSPLL, any selection method, the frequency plan for the DSPLL and whether the DSPLL should be controlled by DCO or not.
15.1.3 Configure outputs
Usage: pll config output <outpin_num> <command> [parameters]
Configure which DSPLL should drive the specified output, what frequency the output should have and whether it’s enabled or disabled.
15.2 Loading
When the configuration is done, this is made effective by the command pll load current.
15.3 Controlling
With the PLL running, some parameters can be changed in runtime. This include enabling and disabling inputs and outputs.
15.3.1 Control input
Usage: pll control input <inpin_num> <command> [parameters]
Enable or disable the specified input.
15.3.2 Control DSPLL
Usage: pll control dspll <dspll_num> <command> [parameters]
Assign a specified input to the specified DSPLL. Only possible if DSPLL is set to manual input selection.
15.3.3 Control Output
Usage: pll control output <outpin_num> <command> [parameters]
Enable or disable the specified output.
16 Further configuration of the M88 Evaluation Kit
For details on how to configure and control the PLL section of the M88, see [1].
