IR Transceivers Have A Very Low Profile

The TFDS6401 and TFDS6402, a pair of fast infrared IrDA-compliant transceiver, stand just 1.8 mm above the printed circuit board. The chips are housed in the company's Dracula package, which mounts to the edge of the pc board to reduce the transceiver's height relative to the board. The devices feature data transmission rates up to 4 Mb/s at 1-meter distances. They can be used to enable infrared links among and between notebook and palmtop computers, digital still and video cameras, cell phones and pagers, and medical and industrial data collection devices. The chips can also be used to enable an exchange of files between these mobile systems and desktop computers, printers, fax machines, photocopiers and set-top boxes. Integrated components include a photo pin diode, a high-power emitter, and low-power analog control circuitry. Pricing is $3.50 each/100,000.
