Vishay transceivers target fast infrared

Amongst the new component offerings from Vishay Intertechnology, Inc. are new infrared transceivers with the fast infrared (FIR) 4Mbit/s data rate required by IrSimpleShot. The new Vishay TFDU6300 and TFDU6301 infrared transceivers support the IrDA high-speed IrSimpleShot protocol for beaming digital pictures directly from camera phones to TVs, printers, and other enabled camera phones.

The FIR 4Mbit/s transceivers feature a miniaturized package that fits easily into today's compact mobile phones, digital still cameras, and TVs. With dimensions of only 2.5 (H) x 3.0 (W) x 8.3-mm (L), the transceivers require minimal battery power, thanks to their low receive operating (or idle) current of 1.8 mA and shutdown current of 0.0-microamp. The transceivers are fully compliant with IrDA Physical Layer, transmitting data over distances upwards of 0.7ms. They can transmit TV remote control signals over distances of up to 25m.

The IrSimpleShot technology was developed by companies including NTT DoCoMo and Sharp to set free the billions of images trapped in camera phones and digital still cameras. Based on proven IrDA and Remote Control technologies, IrSimpleShot allows users to beam photos directly to TVs and printers quickly and easily, without the need for cables or a complicated software set-up.

The operating voltage range of the TFDU6300 and TFDU6301 is from 2.4 V to 3.6 V. The TFDU6300 I/O voltage is dependent on the voltage of the external power supply. The TFDU6301 I/O voltage is 1.8 V, allowing direct connection to a microcontroller's I/Os with 1.8-V logic. Both devices are lead (Pb)-free and capable of lead-free processing in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC. The transceivers have integrated EMI protection so no external shield is required.

Samples and production quantities are available now with lead times of four weeks.
