AD9920ABBCZ集成电路（IC）的模拟前端（AFE）规格书PDF中文资料

AD9920ABBCZ属于集成电路（IC）的模拟前端（AFE）。由亚德诺半导体技术有限公司制造生产的AD9920ABBCZ模拟前端（AFE）模拟前端 (AFE) 是一种用于信号调节的半导体器件，由模拟放大器、运算放大器、滤波器和集成电路构成。这种可配置功能块能连接各种传感器。分辨率范围从 8 位至 42 位不等，通道数范围为 1 至 256 个。

GENERAL DESCRIPTION

The AD9920A is a highly integrated charge-coupled device (CCD) signal processor for digital still camera applications. It includes a complete analog front end (AFE) with analog-to-digital conversion, combined with a full-function programmable timing generator and 19-channel vertical driver (V-driver). The timing generator is capable of supporting up to 24 vertical clock signals to control advanced CCDs. The on-chip V-driver supports up to 19 channels for use with six-field CCDs. A Precision Timing® core allows adjustment of high speed clocks with approximately 400 ps resolution at 40.5 MHz operation. The AD9920A also contains six GPOs that can be used for shutter and system functions.
