Novelda’s X4 is an Ultra-wideband (UWB) short-range impulse radar transceiver System on Chip (SoC). Designed for human presence detection in indoor applications, it offers product innovators a unique combination of reliable, millimetric sensing precision and unobtrusive, intelligent functionality.
As a highly-configurable single-chip solution, X4 is provided in a compact, cost effective and energy efficient chip-scale package. It enables sensors that bring new levels of interactivity and user experience to a variety of applications, including consumer electronic devices and smart building systems.
The X4 is the smallest available radar SoC solution in its class and offers unprecedented human sensing capabilities and BOM cost advantages:
The X4 UWB radar SoC from Novelda is a ground-breaking technology development that enhances all of the key radar operating metrics, including sensitivity, reliability, range, power economy and level of integration. In human presence detection modules, the X4 takes less board space, requires fewer external components, has an industrial temperature rating, and uses the least amount of energy possible.
User detection to enhance interactivity, security and user experience
Occupancy detection to increase comfort levels and save energy
The basic components of the X4 SoC are a transmitter, a receiver, and related control circuits. The system is controlled by the System Controller and is configurable through a 4(6)-wire Serial Peripheral Interface (SPI).
The X4 receive path (RX) consists of a Low Noise Amplifier (LNA), a Digital-to-Analog Converter (DAC), 1536 parallel digital integrators as well as an output memory buffer, accessible through the SPI. The RX is tightly integrated with the transmitter (TX) and is designed for coherent integration of the received energy.
The X4 transmit path (TX) consists of a pulse generator capable of generating pulses at a rate of up to 60.75 MHz. The output frequency and bandwidth are designed to fit worldwide regulatory requirements.
The radar transceiver is able to operate completely autonomously and can be programmed to capture data at predefined intervals and then alert or wake up a host MCU or DSP through dedicated interrupt pins. The Power Management Unit controls the on-chip voltage regulators and enables low-power applications to use efficient duty cycling by powering down parts of the circuit when they are not needed. The system can be configured to consume less than 1mW in idle mode when all analog front end components are turned off.
