2. General description
The Interface Board (IFBD) is custom designed to interface the Telit module variant xE922-3GR with the
Telit Generic Evaluation Board (EVB) thus forming the complete Development Kit of xE922-3GR
The IFBD provides the mapping of Telit module signals and functions into the generic EVB signals and
functions
The xE922-3GR IFBD design includes the following items:
xE922-3GR module
RF SMA connectors
Board to Board connectors for interfacing to EVB main board
Module specific circuitry which is not part of the generic circuitry of the EVB
The IFBD also makes provision to assemble a custom designed module socket instead of assembling the
module.
Power supply and control interface for the RF module is provided from the EVB via the B2B connectors.
To monitor the temperature, a thermistor is placed on the top GND plane, close to the module which should be
representative for the module’s backside temperature.
The bottom plane solder-mask is cutout below the RF module , in order to optimally mount/attach a heatsink
aiming to cool the module via the many heat conducting L1-L8 GND via’s.
The board is designed to accommodate new modules according xE922 FF (34x40mm) LGA 441 pin mapping.

4. 120-Pin male B2B connectors
The interface between IFBD and EVB is implemented via 3pcs of 120p (20p x 6 rows) SAMTEC SEARAY
1.27mm High Speed/High Density B2B connectors (10mm stacking height SEAM/SEAF).
The following tables describe the IFBD B2B connector pin naming. The detailed pin mapping of IFBD to
EVB is described later in the doc

5. Module to EVB Signal Mapping
The below table introduces the mapping of xE922-3GR module pins and functions into the generic EVB
Pin-List and functionality
In many cases the signal names are changed across the platform as many of the EVB signals are simply used
as “pipes” for delivering other functions then initially planned
For this reason the below table is mostly important as it provides:
Actual and most updated pin naming and pin mapping
Actual and most updated pin/signal usage
Actual and most updated pin description and functionality
