TI announces low-power, sub-GHz RF transceiver
The SimpleLink Sub-1 GHz CC1200 supports narrowband and wideband systems, with data rates up to 1Mbps for smart grid, home and building automation, and IEEE 802.15.4g applications.
Why sub-GHz? Well, sub-1GHz RF provides guaranteed full house coverage with a simple star network. It also provides long range for drive by smart meter reading or fixed infrastructure with few concentrators. TI says that wireless ecosystems are evolving with the need to bridge between different technologies and frequency bands.
The RF performance line family to which the CC1200 belongs has some uniquely rich features:
- Strong blocking and selectivity evidenced by 65 dB adjacent channel rejection at 12.5 kHz offset
- 90 dB blocking
- High output power up to +16 dBm and sensitivity of -123 dBm @ 1.2 kbps
- WaveMatch—advanced DSP sync detector with high sensitivity and strong noise immunity
- Advanced RX “sniff” mode-with quick startup and settling time.
What does selectivity and blocking translate into for real life applications?
A flexible RF solution, the CC1200 supports legacy Sub-1 GHz systems, all IEEE 802.15.4g FSK modes with hardware packet handling as well as hardware AES security support and all Wireless M-Bus modes. The CC1200 is aimed at Sub-1 GHz wireless connectivity as well as supporting 169/433/868/920 MHz ISM/SRD bands with possible support for additional frequency bands: 137-160, 205-240 and 274-320 MHz.
Power-down current is 0.3 μA and 0.5 μA sleep current with timer running and 2 mA RX “sniff” mode. Fast transition between power modes help conserve precious battery energy.
