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
20208
RXD 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.
