Vishay Semiconductors

Fast Low Profile (2.5 mm) Infrared Transceiver Module
(MIR, 1.152 Mbit/s) for IrDA

Description

The TFDU5307 is an infrared transceiver module
compliant to the latest IrDA physical layer standard,
supporting IrDA speeds up to 1.152 Mbit/s (MIR) and
carrier based remote control modes up to 2 MHz. Inte­grated within the transceiver module are a PIN photo­diode, an infrared emitter (IRED), and a low-power
control IC to provide a total front-end solution in a sin­gle package.

This Vishay MIR transceiver is built in a low profile
package using the experiences of the lead frame
babyface technology. The transceivers are capable of
directly interfacing with a wide variety of I/O devices,
which perform the modulation/ demodulation function.
At a minimum, a V

bypass capacitor and a serial

CC

Applications

resistor for current control are the only external com­ponents required implementing a complete solution.
TFDU5307 has a tri-state output and is floating in
shutdown mode with a weak pull-up.

3 TXD This Schmitt-Trigger input is used to transmit serial data when SD is low. An on-

chip protection circuit disables the LED driver if the TXD pin is asserted for longer

than 80 μs. When used in conjunction with the SD pin, this pin is also used to

control receiver output pulse duration. The input threshold voltage adapts to and

follows the logic voltage reference applied to the V

4 RXD Received Data Output, push-pull CMOS driver output capable of driving standard

CMOS or TTL loads. No external pull-up or pull-down resistor is required. Floating

with a weak pull-up of 500 kΩ (typ.) in shutdown mode. The voltage swing is

defined by the applied V

5 SD Shutdown. Also used for setting the output pulse duration. Setting this pin active

for more than 1.5 ms places the module into shutdown mode. Before that (t < 0.7
ms) on the falling edge of this signal, the state of the TXD pin is sampled and used

to set the receiver output to long pulse duration (2 µs) or to short pulse duration

(0.4 μs) mode. The input threshold voltage adapts to and follows the logic voltage

reference applied to the V

Definitions:

In the Vishay transceiver data sheets the following
nomenclature is used for defining the IrDA operating
modes:

SIR: 2.4 kbit/s to 115.2 kbit/s, equivalent to the basic
serial infrared standard with the physical layer version
IrPhy 1.0

MIR: 576 kbit/s to 1152 kbit/s
FIR: 4 Mbit/s
VFIR: 16 Mbit/s

MIR and FIR were implemented with IrPhy 1.1, fol­lowed by IrPhy 1.2, adding the SIR Low Power Stan­dard. IrPhy 1.3 extended the Low Power Option to
MIR and FIR and VFIR was added with IrPhy 1.4.A

new version of the standard in any case obsoletes the
former version.

With introducing the updated versions the old ver­sions are obsolete. Therefore the only valid IrDA stan­dard is the actual version IrPhy 1.4 (in Oct. 2002).
