Vishay Intertechnology's TFDU6300 and TFDU6301 FIR transceivers provide the fast infrared (FIR) 4 Mbit/s data rate required by IrSimpleShot in a miniaturized package suitable for mobile phones, digital still cameras and TVs.
With dimensions of only 2.5 mm (H) x 3.0 mm (W) x 8.3 mm (L), the new transceivers require minimal battery power thanks to their low receive operating (or idle) current of 1.8 mA and shutdown current of 0.01 microamperes.
The TFDU6300 and TFDU6301 FIR transceivers are fully compliant with IrDA Physical Layer, transmitting data over distances upwards of 0.7 meters.
Even more importantly for mobile phone manufacturers, they can transmit TV remote control signals over distances of up to 25 meters. The TFDU6300 and TFDU6301 are pin-compatible to Vishay’s TFDU4300 (SIR, 115 kbit/s) and TFDU5307 (MIR, 1 Mbit/s), which allows customers to migrate to faster data rates without changing their existing PCB layout.
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.
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. Samples and production quantities are available now with lead times of four weeks. Pricing for U.S. delivery in quantities of 2 million or more pieces per year is $1.20.
