3.3.4 3-00882B01 FL3X Tiny3 2*100BASE-TX Switch
The FL3X Tiny3 2*100BASE-TX Switch is equipped with one 88E6350RA1 transceiver (PHY) from
Broadcom, which supports two “PC” 100 MBit Ethernet signals (100BASE-TX). This PHY is a switch, was
means the data is switched between the ports. The data is switched to the next Tiny if this is supported by
the next Tiny.

The FL3X Tiny3 4*LIN / 2*SENT is equipped with four TJA1021T transceivers from NXP for LIN and two
discrete SENT transceivers. A dual pole pull-up relay per two LIN channels (A with B and C with D) are also
included, which can pull the buses up to 10V with 1k ohm (Master). Pull-Up setting is saved even if the
device is not powered. Sleep and wakeup functionality are supported for LIN (where LIN_A shares the
wakeup signal with LIN_B and LIN_C shares it with LIN_D). The bypass for data (Ethernet only) switched
between the Tinys is supported by this Tiny.

4Getting Started
4.1 Assembly and Line-up
Read the instructions of the carrier device for more information (see chapter 7.3).
4.2 Configuration and Operation
4.2.1 Termination
Some modules of the FL3X Tiny 3 Family can terminate the connected network. Be sure that the total
network termination is within the network specification.
4.2.2 Termination Matrix
This matrix shows how the terminations would be set.
There are 2 Pins for termination control, so there are just 2 commands (SetTerminationConfigReq Bus A and
SetTerminationConfigReq Bus B) to set terminations. For this reason, some Busses/Channels just can be
set in combination.
The column “I” makes the reference to chapter 3.3.x
The column “FD with D-sub” means for example the Con 2 from the FL3X Device-S
