SEQUANS Communications
Note: The hardware design package of VZM20Q reference design is
available from your Sequans local contact.
1.2 Recommended Design Flow
To ensure that the customer benefits from the details of this document we
recommend to carefully take the following information into account during
the design process.
1.2.1 Design Modifications
Compared to Nimbelink™ reference design, only the following modifications
to the BOM are allowed to designers:
• SIM connector
•Level shifter on UARTs
• Circuitry on RESETN
Note: Any GNSS/GPS function is out of scope of VZM20Q Reference
Design.
Consultancy with Sequans is highly recommended to verify these alternate
preferences.
1.2.2 Schematics Review
Ensuring that the circuit design by analysis will be compliant with the
Sequans’ chipset. It is recommended that the review of the design includes
Sequans’ technical support team.
1.2.3 PCB Placement and Layout Review
To ensure the PCB layout is compliant, it is recommended that the review of
this CAD activity includes Sequans at several iterative steps such as
component placement, RF and digital routing, final layout levels etc. This
might avoid later rework.
