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
mentioned. 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
directly 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
Windows 98
a software upgrade is necessary,
for
Microsoft
drivers are available from SMSC and Vishay
Semiconductor GmbH. This software is intended to
work with Windows 95
, too. Alternatively the
HP/ Sharp settings can be selected. The Microsoft
Operating
Systems
Windows 2000
provide Miniport device drivers.
Mode Switching

Beta 2
and
The TFDU6101E, TFDS6401, TFDS6501E and
TFDT6501E 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 A 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 sequences 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 t
s
≥
200 ns.
3. Set SD/MODE to logic “LOW” (this negative edge
latches state of Txd, which determines speed
setting).
4. After waiting t
h
≥
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.
