applications
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. Inte-
grated within the transceiver module are a PIN photo-
diode, an infrared emitter (IRED), and a low-power
control IC to provide a total front-end solution in a sin-
gle 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/ demodu-
lation function. At a minimum, a V
CC
bypass capacitor
and a serial resistor for current control are the only
external components required implementing a com-
plete solution. TFDU5307 has a tri-state output and is
floating in shutdown mode with a weak pull-up.
