IrDA SIR transceivers in new small package

29 June 2005 Opto-Electronics

Two IrDA serial infrared (SIR) transceivers, claimed to have the smallest available package dimensions on the market, have been introduced by Vishay Intertechnology. The TFBS4650 and TFBS4652 measure 1,6 x 6,8 x 2,8 mm (H x L x D).

These devices are drop-in replacements for the HSDL3208 and HSDL3209, and offer a 25% lower 75 μA idle current and a 36% higher 12,5 mW/sr transmit intensity. Aimed at data transfer applications in mobile phones, camera phones, smart phones, and PDAs, they enable longer on-axis transmit distances with lower power consumption. The TFBS4650/2 also enable mobile phones and PDAs to function as universal remote controls for televisions, DVD players and recorders, and other home appliances over a range of 5,5 m.

The devices' operating voltage range is from 2,4 V to 3,6 V. The TFBS4650 I/O voltage is dependent on the voltage of the external power supply. The TFBS4652 I/O voltage can be as low as 1,5 V, allowing direct connection to a microcontroller's I/Os with 1,5 V or lower logic. Integrated EMI protection eliminates the need for an external shield.

Both devices are lead (Pb)-free and are also fully compliant with IrDA Physical Layer and IEC60825-1 Class 1 Eye Safety specifications.
