Two-TxD Direct Transmission Mode
In the two-TxD direct
transmission mode, the IrDA
(875 nm) LED and the remote
control (940 nm) LED are turned
on separately by two different
input pins. The TxIR input pin is

Shutdown mode*
*The shutdown condition will set the transceiver to the default mode (IrDA-SIR)
Bandwidth Selection Timing
The power on state should be the
IrDA SIR mode. The data transfer
rate must be set by a program-
ming sequence using the TxD_IR
and SD inputs as described below.
Note: SD should not exceed the
maximum, t
C
≤
5

s, to prevent shutdown.
Setting to the High Bandwidth
MIR/FIR Mode (0.576 Mbits/s to
4 Mbits/s)
1. Set SD input to logic “HIGH.”
Wait t

≥
200 ns.
2. Set TxD_IR input to logic
“HIGH.” Wait t
S
≥
50 ns.
3. Set SD to logic “LOW” (this
negative edge latches state of
TxD_IR, which determines
speed setting).
4. After waiting t
H
≥
50 ns
TxD_IR can be set to logic
“LOW.” TxD_IR is now re-
enabled as normal IrDA
transmit input for the High
Bandwidth MIR/FIR mode.
Setting to the Low Bandwidth SIR
Mode (2.4 kbits/s to 115.2 kbits/s)
1. Set SD input to logic “HIGH.”
2. Set TxIR input to logic
“LOW.” Wait t
S
≥
50 ns.
3. Set SD to logic “LOW” (this
negative edge latches state of
TxIR, which determines
speed setting).
4. TxIR must be held for t
S
≥
50 ns. TxIR is now re-enabled
as normal IrDA transmit
input for the Low Bandwidth
SIR mode.
used to turn on the IrDA

input pin is used to turn on the
remote control (940 nm) LED.
