IRDA, TFBS4711

IrDA Transceiver Modules

Integral metal EMI shield
Internal echo-cancel function
Suitable for reflow solderingThe 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 front-end 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 output pulse width is independent of the optical input pulse width and stays always at a fixed pulse width thus making the device optimum for standard endecs. TFBS4711 has a tri-state output and is floating in shut-down mode with a weak pull-up. The shut down (SD) feature cuts current consumption to typically 10 nA.FEATURES
