The CC110L is a cost optimized sub-1 GHz RF transceiver for the 300 - 348 MHz,387 - 464 MHz, and 779 - 928 MHz frequency bands. The circuit is based on the popular CC1101 RF transceiver, and RF performance characteristics are identical. Two CC110L transceivers together enable a low cost bidirectional RF link.
The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 600 kbps.
CC110L provides extensive hardware support for packet handling, data buffering and burst transmissions.
The main operating parameters and the 64- byte receive and transmit FIFOs of CC110L can be controlled via an SPI interface. In a typical system, the CC110L will be used together with a microcontroller and a few additional passive components.

CC110LEM 868/915 MHz参考设计
The CC110LEM 868/915MHz reference design contains schematics and layout files for the CC110LEM module used in the Value Line development kit. The reference design demonstrates good techniques for CC110L decoupling and RF layout. For optimum RF performance, these parts should be copied accurately. This is a 2-layer reference design with a discrete balun and two antenna options:
A small and compact PCB helix antenna that will be useful for applications requiring a high antenna efficiency in a compact area. The 868 MHz PCB helix antenna is only 19 x 12 mm (L x W) and has an efficiency ~70 %. By changing 2 discrete component values, this antenna can also be matched to 915MHz.
A PCB footprint for a single ended 50 ohm antenna. The RF section is designed for operation in the 868 MHz and 915 MHz frequency bands.

CC11xLDK-868-915开发板
The CC11xLDK-868-915 development kit provides a complete hardware performance testing and software development platform for TI’s Sub-1 GHz Value Line. The development kit comes with a pre-programmed packet error rate test. RF range and robustness can be tested with different RF settings, and powerconsumption can be measured easily. This kit supports 868MHz and 915MHz. An extra Evaluation Module Kit (CC11XLEMK-433) is needed to evaluate 433MHz.
The TrxEB, Transceiver Evaluation Board, contains an MSP430 and the following peripherals for prototyping applications:
MSP430F5438 MCU
