This reference design is a complete analog front-end solution for the ADDI9020 and SONY's new CCD image sensor ICX692AQA.
Program advantages and features:
The ADDI9020 is a highly integrated CCD signal processor;
Complete analog front-end circuitry including: black level clamp, variable gain CDS and a 12-bit ADC;
The programmable timing generator provides all the necessary CCD clocks: RG, H clock (5), V clock (12), sensor threshold pulse, base clock, and substrate bias control;
60MHz analog to digital converter;
7 GPIO universal ports for system functions.
System working principle diagram:
The DEMO system block diagram of the video surveillance camera:
The analog front end solution consists of a separate ICX692AQA sensor board and the ADDI9020 evaluation board.
Communicate with the PC via the FPGA main platform
And complete 720p HDMI output through the AD9889B evaluation board
Software Description:
Fully automatic programming
Connect to the FPGA motherboard via USB
Single-step and multi-step control of analog front-end systems
Image acquisition and simple image adjustment
Flexible configuration options to support saving and loading configuration files
Control impedance PCB
Many customers asked us what information we need for impedence control PCB.Here,there are two types for PCB manufacturer,a is single impedance ,just one trace ,two holes .and b is differential impedance,it always go with 1 pair (two trace with same width and space). For single impedance,you just tell us the trace width one which layer and what value you require .For differential impedance,trace width/space,layers and value. Our experience engineers will calculate following your instruction with Polar software.We may change trace width/space or stackup ,but please do not worry, if any changes,we will send you to approve before proceeding. Generally,the tolerance is 10%,and more accurate is 8% .All impedance boards ,we will test here and report.
