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

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.
