Semtech Adds to ISM-Band RF Transceiver Platform and Delivers Industry's Lowest Power Receiver for Long Battery Life Sensors.SX1211 Consumes <3mA in RX Mode, Doubling Battery Life in Wireless Sensor Systems CAMARILLO, Calif. -- Semtech Corp. (Nasdaq:SMTC SMTC Southern Maine Technical College SMTC Science/Mathematics/Technology Center (Central Michigan University) SMTC Saluda Mountain Telephone Company (Knoxville, Tennessee) SMTC Short-To-Medium Term Control ), a leading supplier of analog and mixed-signal semiconductors, today announced the SX1211, a UHF (Ultra High Frequency) The range of electromagnetic frequencies from 300 MHz to 3 GHz. In the U.S., analog television has used UHF channels 52 to 69 in the 700 MHz band. radio frequency (RF) transceiver with the industry's lowest receiver (RX) current consumption (<3mA), significantly increasing battery life in wireless sensor network “WSN” redirects here. For the metasyntax, see Wirth syntax notation. A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as applications. The SX1211 is optimized for asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. sensor network designs in the unlicensed industrial, scientific and medical (ISM) frequency bands (868-870 MHz and 902-928 MHz) where low RX power consumption is critical to battery life as the receiver is constantly waking up to sniff for signals. Key applications include security and alarm systems, sub-metering, industrial monitoring and control, building automation and KONNEX[TM] systems. The SX1211's RX current consumption is up to five times lower than competitive solutions, resulting in up to five years in battery life for sensor applications. In addition to a low RX current, the device also features a 64-byte FIFO (First In First Out) A storage method that retrieves the item stored for the longest time. Contrast with LIFO. See traffic engineering methods. FIFO - first-in first-out buffer that enables more power efficient batch data transfers between the transceiver and microcontroller. Transmit power consumption at + 10 dBm is only 25 mA. With support for both frequency-shift keying (FSK (Frequency Shift Keying) A simple digital modulation technique that uses two frequencies for 0 and 1. See frequency modulation. ) modulation and on-off keying (OOK) modulation, the SX1211 can be used for both new and legacy sensor network designs. The device supports FSK data rates from 1.56 to 100 kbit/s and OOK data rates up to 32 kbit/s. Receiver sensitivity for FSK modulation is -104 dBm at 25 kbit/s and for OOK is -110 dBm at 2 kbit/s. "More automation and security applications are moving to RF with distributed battery powered devices, which is putting more pressure on designers to deliver longer battery life," said Rob Whittaker, Manager, ISM Wireless Product Group in Semtech's Advanced Communications & Sensing Business Unit. "The SX1211 leverages 20 years of low-power RF development to deliver that battery life, along with great signal sensitivity in both FSK and OOK modulation schemes - making it an ideal choice for new or updated designs." The SX1211 is part of Semtech's complete line of ISM-band transceivers, which offer industry leading link budget and power efficient technologies. All major RF communication parameters are programmable and can be configured dynamically, with RF output power programmable up to +12.5 dBm in eight steps. The SX1211 operates over a supply voltage range of 2.1V to 3.6V. It meets regulatory standards for both Europe (ETSI (European Telecommunications Standards Institute, Sophia Antipolis technical park, Nice, France, www.etsi.org) A non-profit membership organization founded in 1988, dedicated to standardizing information and communication technologies (ICT) throughout Europe.
