Texas Instruments Incorporated (TI) today introduced a new member of its high performance sub-1 GHz radio frequency (RF) family providing unmatched connectivity for low-power wireless security, Smart Grid, industrial, healthcare, and home and building automation applications. The new CC1125 sub-1 GHz RF transceiver is the industry's first single-chip solution for wireless social alarms and ultra narrowband applications, targeting ETSI EN 300 220 category 1 (ETSI Cat.1) compliance for the European 869 MHz band. To address the ETSI Cat. 1 standard, one of the world's strictest RF regulations, the CC1125 delivers a 50 percent reduction in system cost and size over discrete designs enabling smaller and more affordable end products. Additionally, the CC1125 can be used in sub-1 GHz applications worldwide that require exceptional RF range and robustness, such as long-range wireless meter reading.
"The new CC1125 transceiver reaffirms our commitment to offer wireless connectivity for any application from the most cost-sensitive to high-performance applications," said Erling Simensen, product marketing manager, wireless connectivity, TI. "Overall, we see an increased interest in ultra narrowband RF ICs like the CC1125 for sub-1 GHz applications that deliver rock-solid wireless connectivity for a variety of applications. With the CC1125 transceiver, manufacturers can now offer ETSI Cat. 1 performance in more affordable and smaller social alarms for Europe's growing elderly population."
