Infrared solutions speeds wireless connectivity
Avago Technologies has added three new highly integrated, high-speed infrared components to its product line. A next-generation fast infrared/very fast infrared (FIR/VFIR) 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. The supplier’s ASDL-7021 supports high-speed infrared (IrDA) transfer speeds, including SIR (115.2 Kbps), MIR (1.152 Mbps), FIR (4 Mbps) and VFIR (16 Mbps).
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 (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. The ASDL-7021 measures 1.2 mm x 4 mm x 4 mm 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 4 Mbps, the ultra-slim ASDL-3023 is a high-performance FIR transceiver capable of transmitting remote control signals over 8 meters 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 1.152 Mbps, 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 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.
