Serial Infrared Transceiver SIR, 115.2 kbit/s,
2.7 V to 5.5 V Operation
Description
The TFBS4710 is a low profile, full range Infrared
Data Transceiver module. It supports IrDA data rates
up to 115.2 kbit/s (SIR). The transceiver module con-
sists of a photo PIN photodiode, an infrared emitter
(IRED), and a low-power CMOS control IC to provide
a total front-end solution in a single package.
The device has a link distance of 1 meter. The RXD
18071
pulse width is independent of the duration of TXD
pulse and always stays at a fixed width thus making
the device optimum for all standard SIR Encoder/
Decoder and interfaces. The Shut Down (SD) feature
cuts current consumption to typically 10 nA.
Features
