Frequently Asked Questions
What frequency band does the XI6843QGABL operate in and why does that matter for indoor sensing?
The device operates from 60 GHz to 64 GHz, providing a 4 GHz sweep bandwidth that yields range resolution finer than 4 cm, enabling accurate occupancy detection and people counting in indoor environments without requiring line-of-sight optical access.
Which processor core is integrated in the XI6843QGABL for on-chip radar signal processing?
The chip integrates an ARM Cortex-R4F processor running at up to 200 MHz, allowing on-chip CFAR detection, FFT processing, and object tracking algorithms to run locally without an external host processor, reducing system latency below 33 ms per frame.
How does the XI6843QGABL achieve angular resolution for multi-person detection scenarios?
The device supports a multiple-input multiple-output antenna configuration with up to 3 TX and 4 RX virtual apertures, delivering azimuth angular resolution of approximately 15 degrees and enabling simultaneous tracking of multiple people within a 120-degree field of view.
Is the XI6843QGABL appropriate for privacy-sensitive occupancy monitoring in offices or healthcare settings?
Yes. Because the 60 GHz radar detects motion and presence without capturing images or audio, it is well-suited for GDPR-compliant occupancy monitoring in offices, hospitals, and restrooms where camera-based sensors would violate privacy, detecting presence at ranges from 0.1 m to roughly 8 m.
What interface does the XI6843QGABL provide for connecting to a host system or microcontroller?
The device offers SPI and UART interfaces for configuration and data output, as well as a dedicated JTAG debug port, enabling integration with popular microcontrollers and single-board computers running at 1.8 V or 3.3 V I/O voltage levels.
