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).
The next-generation vehicles are expected to have even higher-powered batteries, high efficiency battery charging and high performance electric motor systems.
Such highly driven systems will require isolation in the electrical systems to prevent unwanted interference, and provide reliable operation in automotive environments.
The 1Mbaud ACPL-M43T uses a new Avago-developed LED that provides higher light output at lower drive current - 10mA (typical), compared with 16mA for other optocouplers - high common mode rejection (CMR) performance of 30kV/us and a temperature performance range from -40 to +125C.

IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
To increase reliability, an enhanced bonding process for both the integrated circuit and leads provides redundancy and reduces the potential for wire breakage caused by shock and vibration.
The auto-insertable SO-5 surface-mount package (lead-free option available) uses an improved lead frame, which provides better heat dissipation than conventional lead frames.
The ACPL-M43T is ideal for driving intelligent power module (IPM) control electronics in the automotive battery DC/DC convertor and electric motor inverter systems.
In addition, its high-speed operation also makes it perfect for providing digital isolation in robust automotive CANbus serial communication applications.
"Our new automotive optocoupler demonstrates how we will make new inroads as a high-quality supplier in the automotive market, meeting the industry's specifications with stringent design and manufacturing processes to ensure robust and reliable products", said Kheng-Jam Lee, Worldwide Marketing Manager for Isolation Products in Avago Technologies' Optical Communication Solutions Division.
Approval in accordance with the following safety standards is pending: UL 1577 and CSA File CA88324 (Notice 5).
In addition, Avago has created a special reliability and automotive qualification plan to meet the AECQ100 test guidelines for integrated circuits, which was developed by the Automotive Industry Action Group (AIGA).
Avago Technologies' ACPL-M43T optocoupler is available in Samples and production quantities through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
