DW1000 UWB Data manual of transceiver chip for free download

  • DW1000 Is a fully integrated single-chip ultra wideband （UWB） Low power low cost transceiver IC, accord with IEEE802.15.4-2011. It can be used in two-way ranging or TDOA positioning systems , Take the positioning accuracy as 10 Cm of assets . It also supports up to 6.8 Mbps Transmit data at the same rate
  • DW1000 Is a fully integrated low-power single chip CMOS RF transceiver integrated circuit , accord with IEEE802.15.4-2011 UWB standard .DW1000 By an analog front end （ Contains a receiver and a transmitter ） And a digital backend （ Interface with off chip host processor ） form .TX/RX The switch is used to connect the receiver or transmitter to the antenna port . Temperature and voltage monitors are provided on the chip. The receiver consists of an RF front end , The front end amplifies the received signal in a low noise amplifier , Then it is directly converted down to baseband . The receiver is for broadband 、 Linearity and noise figure are optimized . This makes every supported IEEE802.15.4-2011 UWB All channels can be down converted with minimum additional noise and distortion . The baseband signal is demodulated , The received data is obtained by SPI To the main controller .　　 By applying the digitally encoded transmission data to the analog pulse generator , Generate a transmission pulse sequence . The pulse train is up converted by the double balanced mixer to the carrier generated by the synthesizer , And focus on the allowed IEEE802.15.4-2011 One of the UWB On the channel . The modulated RF waveform is amplified before transmission from an external antenna . Integrated circuits have on-chip one-time programmability （OTP） Memory . This memory can be used to store calibration data , Such as Tx Power level 、 Crystal initial frequency error adjustment and range accuracy adjustment . These adjustment values can be automatically retrieved when needed . See the first 5.14 section . When the on-chip voltage regulator is disabled , Normally open can be used （AON） The memory is reserved in the lowest power operation state DW1000 The configuration data . This data will be automatically uploaded and downloaded .DW1000 AON Memory usage is configurable .DW1000 The clock scheme is based on three main circuits ： Crystal oscillator 、 Clock PLL and RF PLL . The on-chip oscillator is designed to use an external crystal in 38.4 Working at megahertz . If there is a properly stable clock elsewhere in the user's system , Then you can use external 38.4 The megahertz clock signal replaces the crystal . The 38.4 The megahertz clock is used as two on-chip PLL The reference clock input of . The clock PLL（ Expressed as CLKPLL） Clock required to generate digital back-end processing signals . The RF PLL generates a down converted local oscillator for the receiving chain （LO）, Generate up converted local oscillator for the emission chain （LO）. Provide an internal 13 kHz oscillator , For sleep state . Host interfaces include slave only interfaces for device communication and configuration SPI. A lot of MAC function , Include CRC Generate 、CRC Check and receive frame filtering .
