MLX75123 Time-of-Flight Companion Chip Datasheet Features & Benefits Description Combines four high speed ADCs with a MLX75123 is a fully integrated companion chip for digital sensor control for Melexis TOF Melexis Time-of-Flight (TOF) sensors. Its perfectly camera sensors suited for automotive and non-automotive Integrated light source control with applications, including, but not limited to, gesture modulation frequencies between recognition, driver monitoring, skeleton tracking, 12-40 MHz people or obstacle detection and traffic monitoring. Programmable modulation frequencies to This sensor interface is designed to connect avoid module to module crosstalk instinctively to any Melexis TOF sensor and the Up to 8 raw phases per frame output can be directly connected to a camera 2 Pre-processed difference & sum output parallel port and I C interface of a microcontroller. modes to reduce the data bandwidth The chip features a configurable sequencer to Continuous or triggered operation modes control the TOF sensor and will sequentially provide 2 Configurable over I C up to 400kHz the 12-bit output data from its four built-in high- 12-bit parallel camera interface up to speed ADCs for an accurate analog to digital 80Mpix/s conversion. Furthermore, MLX75123 synchronously Region of interest (ROI) selection provides the control signals for a modulated light Horizontal & vertical flip/mirror modes source (LED or laser based). Combined with a TOF Per-phase statistics & diagnostics sensor like MLX75023, the MLX75123 offers a cost- Ambient operating temperature ranges effective, integrated, QVGA (320x240) pixel of -20 +85C and -40 +105C resolution camera solution. This chipset can deliver AEC-Q100 qualification available raw TOF data up to 600 frames per second. The device is available in a compact 7x7mm AQFN package and offers a variety of integration possibilities.
