In addition, when connecting the described circuit to
the power supply, low impedance wiring should be
used.
I/O and Software
In the description, already different I/Os are men-
tioned. Differnt combinations are tested and the
function verified with the special drivers available from
the I/O suppliers. In special cases refer to the I/O
manual, the Vishay application notes, or contact di-
rectly Vishay Sales, Marketing or Application.
Control: Differences to TFDx6000 Series
For applications using I/Os from NSC, Winbond and TI
no software upgrade is necessary. In combination with
the latest SMSC controllers for Microsoft Win-
dows 98 a software upgrade is necessary, drivers
are available from SMSC and Vishay Semicon-
ductor GmbH. This software is intended to work with
Windows 95, too. Alternatively the HP/ Sharp set-
tings can be selected. The Microsoft Operating
Systems NT 5.0 Beta 2 and Windows 2000 provide
Miniport device drivers.
Mode Switching
The TFDU610xE, TFDS650xE and TFDT650xE do
not power on with a default mode, therefore the data
transfer rate has to be set by a programming sequence
using the Txd and SD/ Mode inputs as described below
or selected by setting the Mode Pin. The Mode Pin can
be used to statically set the mode (Mode Pin: LOW:
SIR, HIGH: 0.576 Mbit/s to 4.0 Mbit/s). When using
the Mode Pin, the standby current may increase to
about 50 to 60
mA when high or low. If not used or in
standby mode, the mode input should float to minimize
standby current. The low frequency mode covers
speeds up to 115.2 kbit/s. Signals with higher data
rates should be detected in the high frequency mode.
Lower frequency data can also be received in the high
frequency mode but with reduced sensitivity. To switch
the transceivers from low frequency mode to the high
frequency mode and vice versa, the programming se-
quences described below are required.

Setting to the High Bandwidth Mode
(0.576 Mbit/s to 4.0 Mbit/s)
1. Set SD/MODE input to logic “HIGH”.
2. Set Txd input to logic “HIGH”. Wait ts ≥ 200 ns.
3. Set SD/MODE to logic “LOW” (this negative edge
latches state of Txd, which determines speed
setting).
4. After waiting th ≥ 200 ns Txd can be set to logic
“LOW”. The hold time of Txd is limited by the
maximum allowed pulse length.
Txd is now enabled as normal Txd input for the high
bandwidth mode.
