2 General Description V7000, sub-ghz RF transceiver, is designed to address the wireless communications needs for ot applications. t features low-currentt consumption, long-range and wireless w link k robustness, being able to reject the nearby interfering RF signals by moree than 50 db. Spread-spectrum of a crystal oscillator. Varieties of the modulation is employed to extend the coverage while relaxing the stability requirement power-saving modes are developedd to reflect characteristics of ot networks and reduce the power consumption at the system level. With thesee features, V7000 is a perfect fit for applications of ot networks, demanding the wide coverage, long battery life, and reliable link quality. V7000 integrates the RF transmit/receive frontend, RF synthesizer, T/R switches, power amplifiers, and high-dynamic range ADCs. n addition, a 32-bit MCU is integrated for thee radio control and simple protocol processing and S is adopted as thee interface to host thee system. The high-level integration enables low-cost and small footprintt solutions for the ever-increasing demandss of ot networks. Key Features Compliant with EEE g/e Wi-SUN Wireless M-Bus roprietary spread-spectrum modulation for long-range communications Highly linear RF frontend, low-phasee noise RF synthesizer and high-dynamic range ADCs for reliable wireless link Frequency bands:, 315, 433, , , 868, 915, and 950MHz Modulation schemes: K, (G)FSK, 4(G) )FSK, and GMSK Maximum link budget > 160 db Receiver sensitivity Spread-spectrum mode: < -140 dbm Narrowband mode: < -120 dbm Maximum data rate: 400 kbps Transmit output power: +20 dbm / +166 dbm Automatic output power ramping Current consumption Sleep mode: < 1 μa Receive R mode: 12 ma Antenna diversity Fastt AGC for low-power listen mode RF channel c hopping Hardware-based user identification listen to eliminate false system wake-up RSS for listen-before-talk systems Supporting v6 network layer protocol e compliant 6LoWAN adaptation layer with optimized network formation and mesh routing functionn Auto-acknowledgement and re-transmission - 1 -
