7/15/2004 - Agilent Technologies Inc. (NYSE: A) announced the industry's smallest encoder-decoder (EnDec) chip for use in mobile phones and many other applications that require serial infrared (SIR) connectivity. The EnDec features a 75 percent smaller form factor, enabling greater use of infrared (IR) transceivers for point-to-point wireless communications in mobile phones and other small portable devices.
The Agilent HSDL-7002 SIR EnDec, from Agilent's Semiconductor Products Group, measures 0.8 mm high, with a footprint of 4.0 mm x 4.0 mm. It complies with the IrDA (Infrared Data Association) 115.2 kb/s SIR specifications and is supplied in a 16-pin, quad-flat-no lead (QFN) package. The new EnDec provides the same performance as the previous HSDL-7001 SIR EnDec, but features a significantly smaller footprint and 10 to 20 percent reduction in cost.
"The EnDec's miniature size is exactly what our customers need for their smaller portable devices based on chipsets that lack built-in IR support," said Kee Hane Ngoh, vice president and general manager of Agilent's Infrared Products Division. "The device's small size, high performance and reduced cost have been well received."
The EnDec chip provides pulse shaping for the IR transceivers that offer wireless connectivity in applications such as mobile phones, pagers, notebook computers, PDAs, desktop PCs, printers, and handheld data collection terminals. It provides a direct interface between the transceiver and a standard 16550 UART (universal asynchronous receiver-transmitter) or microcontroller. In transmit mode, the EnDec shortens the UART/RS-232 output signal to IrDA-compatible pulses of 1.6 microseconds or 3/16 of the bit duration required to drive the IR transmitter. In receive mode, the EnDec stretches IR pulses to bit widths appropriate to the current operating bit rate, which may range from 1.2 kb/s to 115.2 kb/s.
The Agilent HSDL-7002 is fully compliant with the IrDA Physical Layer 1.4 low power specification from 9.6 kb/s to 115.2 kb/s and the industry-standard 16550 UART specification. It can use an internal or external 3.6864 MHz clock signal, and operates from 2.7 to 5.5V.
U.S. Pricing and Availability
The HSDL-7002 QFN-packaged SIR EnDec IC is available now through Agilent's direct sales channel and worldwide distribution partners. It is priced at $1.30 each in 50,000-unit quantities. More information is available at www.agilent.com/view/ir.
