Infrared Transceiver Module (SIR, 115.2 kbit/s)
for IrDA
Description
The TFDU4300 is a low profile (2.5 mm) infrared
transceiver module with independent logic reference
voltage (V
compliant to the latest IrDA
for fast infrared data communication, supporting IrDA
speeds up to 115.2 kbit/s (SIR) and carrier based
remote control. The transceiver module consists of a
PIN photodiode, an infrared emitter (IRED), and a
low-power control IC to provide a total front-end solu-
tion in a single package.
This device covers an extended IrDA low power range
of close to 1 m. With an external current control resis-
tor the current can be adjusted for shorter ranges.
This Vishay SIR transceiver is built in a new smaller
package using the experiences of the lead frame
BabyFace technology.

optical input pulse width and stays always at a fixed
pulse width thus making the device optimum for stan-
