Description

MLX75123 is a fully integrated companion chip for

Melexis’ Time-of-Flight (TOF) sensors. It’s perfectly

suited for automotive and non-automotive

applications, including, but not limited to, gesture

recognition, driver monitoring, skeleton tracking,

people or obstacle detection and traffic monitoring.

This sensor interface is designed to connect

instinctively to any Melexis TOF sensor and the

output can be directly connected to a camera

parallel port and I

2

C interface of a microcontroller.

The chip features a configurable sequencer to

control the TOF sensor and will sequentially provide

the 12-bit output data from its four built-in high-

speed ADCs for an accurate analog to digital

conversion. Furthermore, MLX75123 synchronously

provides the control signals for a modulated light

source (LED or laser based). Combined with a TOF

sensor like MLX75023, the MLX75123 offers a cost-

effective, integrated, QVGA (320x240) pixel

resolution camera solution. This chipset can deliver

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.
