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 new transceiver is expected to simplify design efforts and reduce time to market.
Prior to STC, all IrDA-compliant optical transceivers required additional mode/sense pins to implement new product features.
STC uses a single three- wire interface to control and program the transceiver for new product features.
This means that it can substantially simplify design efforts by providing a standardized, simplified interface for all future transceivers.
"We have received enthusiastic response for this miniature, low-power, medium infra-red module featuring the IrDA STC interface", said Michael Huether, Director of Marketing Europe, Middle East and Africa, Semiconductor Products Europe.
"It makes it practical to incorporate IR connectivity in virtually any portable application".
The Agilent HSDL-3210 transceiver provides a smart power feature that helps prolong the battery life in ultra-slim cellular phones and PDAs.
This feature allows the optical power to be lowered when the nominal desired link distance is shorter.
The transceiver is capable of operating with logic levels as low as 1.5V and from power sources as low as 2.7V.
This allows the transceiver to work with today's low-power microprocessor chip sets and ASICs that operate at 1.8V or greater signal levels, and in mobile products operating from a single-cell lithium-ion battery.
Typically, the transceiver draws only 10nA of current in shutdown mode, while in standby mode power consumption is only 300uA.
The HSDL-3210 offers 1.15Mbit/s medium infra-red (MIR) datarates and supports infra-red financial management (IrFM) and other data transfers over short distances based on the IrDA's low-power link specification of 20 to 30cm.
It also features one of the smallest footprints in the industry at 2.5 x 8 x 3mm.
The transceiver is IEC60825-1 Class 1 eye safe.
The Agilent HSDL-3210 infra-red transceiver is available through Agilent's distribution partners. Request a free brochure from Avago Technologies ...
