Infrared components offer high-speed wireless connectivity

Barcelona, Spain—Avago Technologies has added three highly integrated, high-speed infrared components to its product line. The ASDL-7021 is a large-scale integration FIR (Fast Infrared)/VFIR (Very Fast Infrared) controller in a 48-pin TFBGA package that measures 1.2-mm x 4-mm x 4-mm. ASDL-7021 supports infrared (IrDA) transfer speeds, including SIR (115.2 Kbits/s), MIR (1.152-Mbits/s), FIR (4-Mbits/s) and VFIR (16-Mbits/s). The ASDL-7021 complements the company's infrared IrDA transceivers and IrSimple protocol software, providing engineers with a comprehensive product for high-speed wireless connectivity.

The ASDL-7021 also includes an on-chip buffer memory and direct memory access (DMA) 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 8-bit memory mapped interface.

Avago also announced two miniature infrared transceivers—the ASDL-3212 and ASDL-3023. Supporting speeds of up to 4-Mbits/s, the ASDL-3023 is a FIR transceiver capable of transmitting remote control signals over 8 meters and has a 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. The ASDL-3212 transfers data at 1.152-Mbits/s and offers smart IOVCC input for a flexible, low-voltage range logic interface and extended link distance capability. It is housed in a 1.64 mm x 2.73 mm x 7 mm, ChipLED, lead-free surface mount package.

Pricing: For the ASDL-7021 begins at $2.50 in moderate volumes; the ASDL 3212 is priced at $1.00 and ASDL-3023 is priced at $1.50 in moderate volumes.
Availability: All three products are available now through Avago's direct sales channel and worldwide distribution partners.
