Agilent Technologies has introduced a series of surface-mount LEDs designed and qualified specifically for automobile interior and exterior lighting applications.
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).
It operates from supply voltages as low as 2.4V and can interface to input/output logic circuits with logic-high levels down to 1.5V.
The infra-red transceiver's low-power operation and small size help reduce cost and board space.
The HSDL-3209 infra-red transceiver, from Agilent's Semiconductor Products Group, features an extended link distance up to 500mm and is ideally suited for secure IrFM (infra-red financial messaging) wireless point-and-pay applications, which are becoming popular in Japan and Korea.
IrFM point-and-pay enables users to perform wireless financial transactions between a mobile device and either a point-of-sale terminal or an ATM, kiosk and vending machine equipped with an infra-red port.
The Agilent HSDL-3209 transceiver supports the IrDA (Infra-red Data Association) 1.4 low-power specification and operates at transmission speeds ranging from 9.6 to 115Kbit/s.
Its 1.5V logic interface allows the transceiver to work with low-power microprocessor chipsets and ASICs that operate at 1.5V or greater signal levels without the need for logic-level shifter circuits, and in mobile products operating from a single lithium-ion cell.
The new transceiver module offers guaranteed performance over the -25 to +70C temperature range. Request a free brochure from Avago Technologies ...
