Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
Avago's ASDL-7021 supports high-speed infra-red (IrDA) transfer speeds, including SIR (115.2Kbit/s), MIR (1.152Mbit/s), FIR (4Mbit/s) and VFIR (16Mbit/s).
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 I/O and memory from its system bus.
Encoding and decoding IR signals, the ASDL-7021 serves as an interface to a host microcontroller using an 8bit memory mapped interface.
The ASDL-7021 measures 1.2 x 4 x 4mm and is available in a 48-pin, TFBGA package.
Avago also announced two miniaturised infra-red transceivers, the ASDL-3212 and ASDL-3023.
Supporting speeds up to 4Mbit/s, the ultraslim 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 1.152Mbit/s 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 x 2.73 x 7mm, ChipLED, lead-free surface mount package.
The market for infra-red 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.
All three products are available now through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
