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
3. Set SD to logic “low” (this negative edge latches state of
4. TXD must be held for t
TXD is now enabled as normal TXD input for the high
bandwidth mode.
Note
When applying this sequence to the device already in the lower
bandwidth mode, the SD pulse is interpreted as shutdown. In this
case the RXD output of the transceiver may react with a single pulse
(going active low) for a duration less than 2 µs. The operating
software should take care for this condition.
In case the applied SD pulse is longer than 4 µs, no RXD pulse is to
be expected but the receiver startup time is to be taken into account
before the device is in receive condition.
RECOMMENDED SOLDER PROFILES
Solder Profile for Sn/Pb Soldering
Lead (Pb)-free, Recommended Solder Profile
The TFDU6300 is a lead (Pb)-free transceiver and qualified
for lead (Pb)-free processing. For lead (Pb)-free solder paste
like Sn
profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike
(RTS). The Ramp-Soak-Spike profile was developed
primarily for reflow ovens heated by infrared radiation. With
widespread use of forced convection reflow ovens the

Ramp-To-Spike profile is used increasingly. Shown in
figure 4 and 5 are Vishay’s recommended profiles for use
with the TFDU6300 transceivers. For more details please
refer to the application note “SMD Assembly Instructions”.
A ramp-up rate less than 0.9 °C/s is not recommended.
Ramp-up rates faster than 1.3 °C/s could damage an optical
part because the thermal conductivity is less than compared
to a standard IC.
Wave Soldering
For TFDUxxxx and TFBSxxxx transceiver devices wave
soldering is not recommended.
Manual Soldering
Manual soldering is the standard method for lab use.
However,
recommended because the risk of damage is highly
dependent on the experience of the operator. Nevertheless,
we added a chapter to the above mentioned application note,
describing manual soldering and desoldering.
Storage
The storage and drying processes for all Vishay transceivers
(TFDUxxxx and TFBSxxx) are equivalent to MSL4.
The data for the drying procedure is given on labels on the
packing and also in the application note “Taping, Labeling,
Storage and Packing”.
