The ATA8352 device is a low-power Ultra-Wide-Band (UWB) transceiver with integrated security layer for secure distance bounding, localization and point-to-point data communication. The ATA8352 device’s digital transmitting circuitry ensures maximum flexibility in the generation of UWB pulse signals. The transmitter is able to: • Generate accurate pulse durations ranging from less than 1 ns to more than 10 ns with controlled envelope shape • Generate timestamps during the receive and the transmit mode for Time-Difference-of-Arrival (TDoA) measurements • Generate a carrier frequency between 6.2 GHz and 8.3 GHz • Ensure ETSI and FCC regulation compliance with programmable transmitted peak output power up to a typical value of 11 dBm The ATA8352 Front-end (FE) receiver provides an excellent sensitivity to guarantee a superior link budget for the RF communication. The digital base band signal processing unit ensures a highly stable sub nanosecond Time-of-Arrival (ToA) estimation. The ATA8352 includes a MAC layer for secure distance-bounding measurement and data communication for proximity-based access control. The layer can be configured to ensure different degrees of security while providing a sufficient number of distance measurements to be run in one secure access control session.
