TFDU5307
Vishay Semiconductors
Fast Low Profile (2.5 mm) Infrared Transceiver Module
®
(MIR, 1.152 Mbit/s) for IrDA 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 resistor for current control are the only external com-
package using the experiences of the lead frame ponents required implementing a complete solution.
