Řada RF produktů Sub-1GHz Value Line
Texas Instruments představuje unifikovanou řadu obvodů pro radiofrekvenční komunikaci ve frekvenčních pásmech do 1 GHz. Obvody CC115L (vysílač), CC113L (přijímač) a CC110L (přijímač/vysílač) jsou určeny pro běžně používané modulační formáty 2-FSK, 4-FSK, GFSK a OOK.
Jak již název řady Value Line napovídá, jsou u těchto obvodů velmi zajímavé cenové podmínky. Jejich kusová cena ve vysokých objemech klesá pod 1 USD. Obvody jsou také pinově a softwarově plně kompatibilní s obvody CC1101.

“TI's new Sub-1 GHz RF Value Line answers the market's increasing need for simple, low-cost connectivity for applications that require both long battery life and long range wireless connection,” said Erling Simensen, product marketing manager, Low-Power RF, TI. “Designs based on the Sub-1GHz RF Value Line family not only ease connectivity integration efforts for engineers, but promise wireless connectivity for more of today's cost-sensitive consumer applications.”
The CC11xLDK-868-915 and CC11xLEMK-433 development kits provide complete hardware performance testing and software development platforms for the new product family. The kits also offer new low-cost reference designs, with a compact PCB antenna for 433, 868, 915 MHz, featuring a reduced component count and complete design ready for FCC and ETSI certification. The small-size, compact PCB helix antenna represents only a quarter of the size of previous PCB antennas, and is useful for applications requiring high antenna efficiency in a compact area.
