I/O and Software
In the description, already different I/Os are men-
tioned. Different 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.
Mode Switching
The TFDU5103 is in the SIR mode after power on as
a default mode, therefore the FIR data transfer rate
has to be set by a programming sequence using the
Txd and SD 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 1.152 Mbit/s). If not used or in standby
mode, the mode input should float or should not be
loaded with more than 50 pF. The low frequency
mode covers speeds up to 115.2 kbit/s. Signals with
higher data rates should be detected in the high fre-
quency mode. Lower frequency data can also be
received in the high frequency mode but with reduced
sensitivity. To switch the transceivers from low fre-
quency 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 1.152 Mbit/s)
1. Set SD input to logic "HIGH".
2. Set Txd input to logic "HIGH". Wait t
s
≥
200 ns.
3. Set SD 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 maxi-
mum allowed pulse length.
After that Txd is enabled as normal Txd input and the
transceiver is set for the high bandwidth (576 kbit/s to
1.152 kbit/s) mode.
Setting to the Lower Bandwidth Mode
(2.4 kbit/s to 115.2 kbit/s)
1. Set SD input to logic "HIGH".
2. Set Txd input to logic "LOW". Wait t
s
≥
200 ns.
3. Set SD to logic "LOW" (this negative edge latches
state of Txd, which determines speed setting).
4. Txd must be held for t
h
≥
200 ns.
After that Txd is enabled as normal Txd input and the
transceiver is set for the lower bandwidth (9.6 kbit/s to
115.2 kbit/s) mode.
