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 is a leading supplier of innovative semiconductor solutions for advanced communications, industrial and commercial applications.
CMR is the maximum slew rate of common mode voltage (VCM) which can be sustained, keeping the output in the correct logic state.
CMR failure results in glitching on the output as either a positive or negative pulse.
This key specification guarantees the reliable transfer of drive information at very high DC-link voltage and over fast switching operations.
Avago's new ACPL-3130, ACPL-J313 and ACNW-3130 gate drive optocouplers are ideal for applications such as isolated IGBT/ MOSFET-gate drives for industrial inverters, switching power supplies (SPS) and uninterruptible power supplies.
The optocouplers deliver 2.5 A maximum peak output current.
Additionally, the products support a wide operating voltage range (15 to 30 volts) required by gate-controlled devices.
"Avago Technologies continues to be ahead of the curve by delivering a superior optocoupler product with the industry's highest CMR ratio," said Kheng-Jam Lee, worldwide marketing manager of Avago Technologies' Optical Communication Solutions Division.
"We've exploitd our technical strength in proprietary shielding technology and unique package design to deliver a timely solution for industrial applications".
"The addition of these products enables us to provide the broadest portfolio of high-quality, isolated gate drive optocouplers on the market".
As part of Avago's extensive range of high-performance, isolated, gate drive optocouplers, the ACPL-3130 contains a GaAs LED while the ACPL-J313 and ACNW-3130 contain an AIGaAs LED.
The new optocouplers have received approval in accordance with the following safety standards: UL (pending), CSA (pending) and IEC/EN/DIN EN 60747-5-2. Request a free brochure from Avago Technologies ...
