•FlexCard PCIe3
NOTICE
Please check the manual of your carrier device which FlexTiny 3 is supported
before using a dedicated FlexTiny 3!
2.2 Accessory Parts
For usage of FlexTiny 3 Family, the following parts are necessary:
•FlexDevice-S/L/L²/HD-sub or FlexCard PXIe3/PCIe3 (carrier device)

FlexTiny 3 Family modules are inverse polarity protected by polarized connectors.
NOTICE
EMC
The FlexTiny 3 Family modules contain EMC filter parts. Anyhow, regarding the
high bus frequencies the most bus lines on the carrier board need to be
symmetrical and as short as possible. Use cable with differential pair technology
for 2-wire-buses to provide noise immunity!

which supports three “100BASE-T1” 2-wire 100 MBit Ethernet signals. 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.
NOTICE
A maximum of three FlexTiny3 3-00882D01 can be used at the same time per
device.

3.3.6 3-00882G01 FlexTiny3 3 ETH BR switch (100BASE-T1)
The FlexTiny 3 3 ETH BR switched is a special Tiny formed as a “L” which uses 3 Tiny slots. The Tiny is
equipped with three BCM89500BQLEG transceiver (PHY) from Broadcom, which each of them supports
three “100BASE-T1” 2-wire 100 Mbit Ethernet signals. The PHYs are switches, which means the data is
switched between the ports and themselves. The data is switched to the next Tiny is supported by this
Tiny.
NOTICE
This FlexTiny3 cannot be used with the FlexDevice-S.

3.3.8 3-00884A02 FlexTiny3 LIN SENT
The FlexTiny 3 LIN 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 FlexTiny 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 FlexDevice-S
