Description

The TFBS4711 is a low profile, Infrared Data Transceiver 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 frontend solution in a single package.

The device is designed for the low power IrDA standard 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 making the device optimum for all standard SIR Encoder/ Decoder and interfaces. The Shut Down (SD) feature cuts current consumption to typically 10 nA.
