Serial Infrared Transceiver SIR, 115.2 kbit/s,

2.7 V to 5.5 V Operation

Description

The TFBS4711 is a low profile, Infrared Data Trans-

ceiver module. It supports IrDA data rates up to

115.2 kbit/s (SIR). The transceiver module consists of

a 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 is designed for the low power IrDA stan-

dard with an extended range on-axis up to 1 m. The

RXD pulse width is independent of the duration of

TXD pulse and always stays at a fixed width thus
