Avago Technologies infrared solutions make high-speed wireless connectivity possibile

Avago Technologies have added three new highly integrated, high-speed infrared components to its product line. The company is a leading supplier of innovative semiconductor solutions for advanced communications, industrial and commercial applications. A next- generation, large-scale integration FIR (fast infrared)/VFIR (very fast infrared) controller in a TFBGA package, the ASDL-7021 complements Avago's broad portfolio of infrared IrDA^® transceivers and IrSimple protocol software to provide design engineers with a comprehensive solution for high-speed wireless connectivity. Avago's ASDL-7021 supports high-speed infrared (IrDA) transfer speeds, including SIR (115.2Kbps), MIR (1.152Mbps), FIR (4Mbps) and VFIR (16Mbps).

As a single chip solution that integrates all necessary hardware to implement IrDA, the ASDL-7021 also includes an on-chip buffer memory and direct memory access that enables it to access peripheral IO and memory from its system bus. Encoding and decoding IR signals, the ASDL-7021 serves as an interface to a host microcontroller using an eight-bit memory mapped interface. The ASDL- 7021 measures 1.2 × 4 × 4mm and is available in a 48-pin, TFBGA package.

Avago also announced two miniaturized infrared transceivers, the ASDL-3212 and ASDL-3023. Supporting speeds of up to 4Mbps, the ultra-slim ASDL-3023 is a high- performance FIR transceiver capable of transmitting remote control signals over 8m and has an exclusive power saving feature that allows design engineers to achieve superior power consumption with no compromise in performance. The ASDL-3212 is a small form factor MIR transceiver transferring data at 1.152Mbps which offers smart IOVCC input for a flexible, low-voltage range logic interface and extended link distance capability. It is developed in a 1.64 × 2.73 × 7mm, ChipLED, lead- free surface mount package.

The market for infrared technologies continues to grow as more handheld devices, such as mobile handsets, PDAs and industrial handheld terminals, require a variety of wireless connectivity options. Higher speed IrDA transceivers and IrSimple protocols provide mobile devices with the fastest data transfer time, lower power consumption and higher security features at a much lower design cost.

Availability

All three products are available now through Avago's direct sales channel and worldwide distribution partners.
