2. GENERAL PRODUCT DESCRIPTION
Overview
The Translation Board (TLB) is custom designed to interface the Telit module variant
FN980m with the Telit Generic Evaluation Board (EVB) thus forming the complete
Development Kit of FN980 Family.
The TLB provides the mapping of Telit module signals and functions into the generic EVB
signals and functions.
The FN980 Family TLB design includes the following items:
•FN980 Family 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 TLB 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 GND
via’s.
The board is designed to accommodate new modules according FN980 Family M.2 (50 x
30.00 x 3.40mm, +/- 0.15 mm tolerance and 75 pins) updated pin mapping.

2.3.2. Jumper Description
(1) When using TGPIO_05 as I2S_CLK (Default)
The I2S function can be evaluated using the audio codec implemented in EVB.
Check out the AT#DVI section of the FN980 Family AT Commands Reference
Guide.

1VV0301651 Rev. 2 Page 14 of 38 2021-02-24
(2) When using TGPIO_05 as USB/PCIe Switch Feature
FN980 family support USB/PCIe switch feature which is switching between USB
and PCIe for Network Interface.
Check out the AT#USBPCISWITCH section of the FN980 Family AT Commands
Reference Guide.
(3) SIM select
PL215 is not currently used. Leave it floating.
(4) 3.3V PCIe/USB (Default)
By connecting PL301/PL302,
- 3.3V power is supplied to the USB switch block, so USB 3.1 gen2 can be
supported by using Type C connector.
- When FN980 family operates as PCIe EP, it can be supplied VBATT from host
through SO301.
(5) W_DISABLE_N

FN980 Family TLB HW Design Guide
1VV0301651 Rev. 2 Page 15 of 38 2021-02-24
Connecting a jumper to PL201 triggers the W_DISABLE_N function. (Power
Saving Mode)
Check out the AT#PSMWDISACFG section of the FN980 Family AT Commands
Reference Guide.
(6) Auto Power ON (Default)
If PL214 1-2 is connected by jumper, then FN980 will be automatically powered on
when the VBATT is supplied.

2.6.1. End Point
First, enter the following command AT#USBPCISWITCH=1,5
Then USB/PCIe switch feature is enable and will be triggered by TGPIO05.
Please refer to AT#USBPCISWITCH section of the FN980 Family AT Commands
Reference Guide for more details.
And set the jumper as shown below.
Now FN980 family will operated as PCIe EP by connecting it to the host using an
extension cable.

1VV0301651 Rev. 2 Page 19 of 38 2021-02-24
If you want to use USB as a network interface again, just disable the USB/PCIe function,
or move the jumper as shown below and reboot the module.

2.6.2. Root Complex
Since FN980 is made according to the m.2 card standard, it basically operates as EP.
If you want to run FN980 as RC using PCIe 64pin connector, you need to move 4 optional
resistors referring to the figure below.
Otherwise there are FT980 series routers equipped with the FN980 family.
It supports functions such as PCIe to Ethernet, USB 3.1 gen 2, and mmWave.
