Responding to the volumetric constraints of today’s
ultra-compact and power conscious portable products, Vishay has developed the next generation in
infrared wireless communication transceivers. The
transceiver has been designed to support up to 4
Mbit/s IrDA, HP-SIR, Local Talk and Sharp
ASK modes. The device combines an LED, photodiode, LED driver and a fully differential receiver into a
single integrated package.

Function
RxD
Output
Active
Low
This output indicates received serial data. It is a push-pull CMOS driver capable of driving a standard CMOS or TTL load. No external pull-up or pull-down resistor is required.
This output may switch indeterminately when the module is transmitting. This output pin
is in tri-state mode when the module is in shutdown mode and during digital serial programming operations. RxD is high at initializaton.
TxD
Input
Active
High
This CMOS input is used to transmit serial data when SD/ Mode is low. An on-chip protection circuit disables the LED driver if the TxDpin is asserted for longer than 60 µs.
When used in conjunction with the SD/ Mode pin. TxD is low at initializaton.
SD/ Mode Input
Active
High
Assertion of this pin high for a period of time exceeding 400 µs places the module into
shutdown mode. On the falling edge of this signal, the state of the TxDpin is sampled and
used to set receiver low bandwidth (TxD= Low) or high bandwidth (TxD= High) mode.
See Figures 7 and 8 for timings. SD is low at initializaton
VCC
Positive Supply
-
Connect to positive power supply (2.7 V to 5.25 V). Placement of a 1.0 µF to 10.0 µF decoupling ceramic capacitor as close as possible to the V CC pin is recommended.
GND
Ground (Power)
-
Connect to power supply ground. A solid ground plane is recommended.
NC
No Connect
-
This pin could be connected to ground.
LEDA
Input
-
This pin can be connected directly to VCC. No series resistor is required.
LEDC
Output
-
LED cathode. Leave this pin unconnected. This pin may be monitored to determine the
state of the LED.

The transceiver powers on with the receiver in low bandwidth
mode. To enable high bandwidth mode, apply timings as
shown in the figure 7, to the SD/ Mode and the TxD inputs.
Note that the internal LED driver is disabled when SD/ Mode is
active and is not enabled until the next rising edge of TxD. This
ensures that the LED will not be active during bandwidth
adjustment. It is recommended that the SD/ Mode pin be connected to GND if bandwidth adjustment and shutdown mode
are not used.
Setting the Receiver to High Bandwidth Mode (see Figure 4)
1. Set the SD/ Mode input to ’logic high’.
2. Set the TxD input to ’logic high’. Wait tsu ≥ 10 ns.
3. Set the SD/ Mode to ’logic low’. (This high-to-low transition
latches the state of TxD, which determines the receiver
bandwidth.)

4. After waiting th ≥ 10 ns, set the TxDinput to ’logic low’. The
receiver is in high bandwidth mode within 200 µs of the SD/
Mode rising edge or 10 ns after the SD/ Mode falling edge,
whichever occurs later.
Setting the Receiver to Low Bandwidth Mode (see Figure 4)
1. Set the SD/ Mode input to ’logic high’.
2. Ensure that the TxD input is at ’logic low’. Wait tsu ≥ 10 ns.
3. Set the SD/ Mode to ’logic low’. (This high-to-low transition
latches the state of TxD, which determines the receiver
bandwidth.)
4. Ensure that the TxD input remains low for th ≥ 10 ns. The
receiver is in low bandwidth mode within 200 µs of the SD/
Mode rising edge or 10 ns after the SD/ Mode falling edge,
whichever occurs later.
