ADI ADDI9036CCD飞行时间(TOF)信号处理器应用方案

ADI公司的ADDI9036是用于电荷耦合器件(CCD)飞行时间(TOF)图像应用的完整的45MHz的前端解决方案.包括有模拟前端(AFE),可编指令集架构(ISA)计时发生器(ISATG),7路激光二极管(LD)驱动器,7路H驱动器和16路垂直驱动器(V驱动器).其精密计时核允许调整CCD水平时钟和LD输出,具有大约174ps分辨率和45MHz工作频率.AFE包括黑暗电平钳位, 相关双采样器(CDS),可变增益放大器(VGA)和12位模数转换器(ADC).AFE数据通过MIPI® CSI-2发送接口进行输出.内部的寄存器可通过I2C串行接口进行编程. ADDI9036采用6 mm × 6 mm, 117点WLCSP封装,工厂作温度−20C 到+85C.主要用在机器人,工业自动化,SLAM(同时定位和地图构建),增强现实,虚拟现实和无人机以及汽车检测.本文介绍了ADDI9036主要特性,功能框图以及3D飞行时间开发平台AD-96TOF1-EBZ高档主要指标,激光发送器板和AFE接收器板框图,与主要部件,电路图和材料清单以及飞行时间系统(ToF)框图.

 

 The ADDI9036 is a complete, 45 MHz, front-end solution for charge coupled device (CCD) time of flight (TOF) imaging applications. The ADDI9036 includes an analog front end (AFE), a programmable instruction set architecture (ISA) timing generator (ISATG), a 7-channel laser diode (LD) driver, a 7-channel H-driver, and a 16-channel vertical driver (V-driver). The Precision Timing® core allows adjustment of the CCD horizontal clocks and LD outputs with approximately 174 ps resolution at 45 MHz operation.

The AFE includes black level clamping, a correlated double sampler (CDS), a variable gain amplifier (VGA), and a 12-bit analog-to-digital converter (ADC). T
