Vishay Intros TFBS6711/TFBS6712 IrDA Transceivers
Vishay Intertechnology Inc. (Malvern, PA) introduced its new fast infrared (FIR) IrDA® transceivers, which work over a typical distance of 50 cm at data rates up to 4 Mbit/sec. The new TFBS6711 and TFBS6712 transceivers enable mobile phones and PDAs to function as universal remote controls for televisions, DVD players/recorders, and other home appliances.
The TFBS6711 and TFBS6712 are capable of transmitting remote control signals over a distance of 6.5 m. The transceivers feature an emitter with a wavelength that is closely matched to remote control receivers. 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. The operating voltage for both transceivers is 2.4 V to 3.6 V. Both devices feature a shutdown current of 0.01 µA and an idle supply current of 1.7 mA.
With a height of 1.9 mm and footprint dimensions of 6.0 mm x 3.0 mm, the TFBS6711 and TFBS6712 are lead-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. Pricing for US delivery is $2.00 for 100,000 units per year.
