IrDA Transceivers have 1.9 mm profile and 4 Mbps data rate.
July 19, 2005 - Measuring 6.0 x 3.0 x 1.9 mm, TFBS6711 and TFBS6712 FIR (fast infrared) IrDA transceivers work over typ distance of 50 cm. They enable mobile phones and PDAs to function as universal remote controls and can transfer 329 kbyte, 1280 x 960 pixel image in 1.5 sec. Capable of transmitting remote control signals over 6.5 m distance, lead (Pb)-free products feature 2.4–3.6 V operating voltage, 0.01 A shutdown current, and 1.7 mA idle supply current.

Vishay Targets Mobile Phones with New 1.9-mm-High IrDA Transceivers, Industry's Smallest with 4-Mbit/s FIR Data Rate
MALVERN, PENNSYLVANIA - July 11, 2005 - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the industry's smallest FIR (fast infrared) IrDA transceivers. With a height of only 1.9 mm and footprint dimensions of 6.0 mm by 3.0 mm, the new TFBS6711 and TFBS6712 are the thinnest, smallest FIR transceivers on the market.
For IrDA communication, the new transceivers work over a typical distance of 50 cm at data rates up to 4 Mbit/s. They also enable mobile phones and PDAs to function as universal remote controls for televisions, DVD players/recorders, and other home appliances. Previously, designers needing a low-profile transceiver were forced to choose a relatively slow SIR (serial infrared) transceiver. With the TFBS6711 and TFBS6712, Vishay gives mobile phone and PDA design engineers the speed they require in an exceptionally small package.
In the camera phone market, sharing and printing digital pictures using IrDA transceivers has gained in popularity, said Dr. Heinz Nather, Vice President of Vishay's Sensors and IRDC Division. As camera resolution increases, data transfer time becomes a concern. Using Vishay's TFBS6711 or TFBS6712 transceivers, a 329-kbyte 1280 x 960-pixel image can be transferred in 1.5 seconds; 25 seconds faster than SIR. That is a big advantage for our customers.
The TFBS6711 and TFBS6712 are also capable of transmitting remote control signals over a distance of 6.5 meters. Leveraging Vishay's experience in this application, these transceivers feature an emitter with a wavelength that is closely matched to remote control receivers. By using the TFBS6711 or TFBS6712 in a mobile phone, for example, design engineers can meet their IR remote control distance requirements without having to add a second, bulky emitter.
The TFBS6711 I/O voltage is defined by the external power supply voltage. The TFBS6712 I/O voltage equals 1.8 V, allowing direct connection to a microcontroller operating at 1.8 V. Operating voltage for both transceivers is 2.4 V to 3.6 V. Both devices feature a shutdown current of 0.01 A and an idle supply current of 1.7 mA, roughly half that of the next closest FIR transceiver on the market.
The TFBS6711 and TFBS6712 are lead (Pb)-free and capable of lead free processing and are in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC. The transceivers are fully compliant with IrDA Physical Layer and IEC60825-1 Class 1 Eye Safety specifications.
Samples and production quantities are available now, with lead times of six weeks.
