TFBS4711  
Vishay Semiconductors  
Serial Infrared Transceiver SIR, 115.2 kbit/s, 2.4 V to 5.5 V Operation  
FEATURES  
• Compliant with the latest IrDA physical layer low  
power specification (9.6 kbit/s to 115.2 kbit/s)  
• Small package (H x L x W in mm): 1.9 x 3 x 6  
• Typical link distance on-axis up to 1 m  
• Battery and power management features:  
20208  
> Idle current - 70 µA typical  
> Shutdown current - 10 nA typical  
> Operates from 2.4 V to 5.5 V within specification over full  
temperature range from - 25 °C to + 85 °C  
DESCRIPTION  
The TFBS4711 is a low profile, infrared data transceiver  
module. It supports IrDA® data rates up to 115.2 kbit/s (SIR).  
• Remote control - transmit distance up to 8 m  
• Tri-state receiver output, floating in shutdown with a weak  
pull-up  
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.  
• Constant RXD output pulse width (2.2 µs typical)  
• Meets IrFM fast connection requirements  
• Split power supply, an independent, unregulated supply for  
IRED anode and a well regulated supply for VCC  
• Directly interfaces with various super I/O and controller  
devices and encoder/decoder such as TOIM4232 or  
TOIM5232  
• Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)  
APPLICATIONS  
• Ideal for battery operated devices  
• PDAs  
• Compliant to RoHS directive 2002/95/EC and in  
accordance to WEEE 2002/96/EC  
• Mobile phones  
• Electronic wallet (IrFM)  
• Notebook computers  
• Digital still and video cameras  
• Printers, fax machines, photocopiers, screen projectors  
• Data loggers  
• External infrared adapters (dongles)  
• Diagnostics systems  
• Medical and industrial data collection devices  
• Kiosks, POS, point and pay devices  
• GPS  
• Access control  
• Field programming devices
