Pre-Release Information
received in high frequency mode with reduced sensitivity.
To switch the transceivers from low frequency mode to
the 4.0 Mbit/s mode and vice versa, the programming
sequences described below are required.

High: FIR
Low: SIR
Setting to the High Bandwidth Mode (0.576 to
4.0 Mbit/s)
1. Set SD/MODE input to logic ”HIGH”.
2. Set Txd input to logic ”HIGH”. Wait t
s
3. Set SD/MODE to logic ”LOW” (this negative edge
latches state of Txd, which determines speed setting).
4. After waiting t

200 ns Txd can be set to logic
”LOW”. The hold time of Txd is limited by the
maximum allowed pulse length.
200 ns.
Txd is now enabled as normal Txd input for the high
bandwidth mode.
Setting to the Lower Bandwidth Mode (2.4 to
115.2 kbit/s)
1. Set SD/MODE input to logic ”HIGH”.
2. Set Txd input to logic ”LOW”. Wait t

Txd is now enabled as normal Txd input for the lower
bandwidth mode.
