8/6/2002 - Agilent Technologies introduced the HSDL-3210, the industry's first infrared (IR) transceiver that supports the IrDA Serial Transceiver Control (STC) bus used in ultra-slim cellular phones and personal digital assistants (PDAs). The STC provides a common pin layout interface that enables portable-product designers to add new features using fewer pins and accommodate frequent design changes. 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 infrared module featuring the IrDA STC interface," said Kee Hane Ngoh, operations manager of Agilent's Infrared Products Operation. "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 1.5 volts and from power sources as low as 2.7 volts. This allows the transceiver to work with today's low-power microprocessor chip sets and ASICs that operate at 1.8 volt or greater signal levels, and in mobile products operating from a single-cell lithium ion battery. Typically, the transceiver draws only 10 nA of current in shutdown mode, while in standby mode power consumption is only 300 uA.
The HSDL-3210 offers 1.15 Mb/s medium infrared (MIR) data rates and supports infrared financial management (IrFM) and other data transfers over short distances based on the IrDA's low-power link specification of 20 cm to 30 cm. It also features one of the smallest footprints in the industry at 2.5 mm (height) by 8 mm (width) by 3 mm (depth). The transceiver is IEC 60825-1 Class 1 Eye Safe.
The Agilent HSDL-3210 infrared transceiver is currently available for volume order through Agilent's sales offices worldwide. The transceiver also is available through Agilent's distribution partners. Further information on Agilent's IR transceivers is available at www.agilent.com/view/ir
