Description: TLV1544与TMS320VC5402通过串行口连接，此时，A／D转换芯片作为从设备，DSP提供帧同步和输入／输出时钟信号。TLV1544与DSP之间数据交换的时序图如图3所示。
开始时， 为高电平（芯片处于非激活状态），DATA IN和I/OCLK无效，DATAOUT处于高阻状态。当串行接口使CS变低（激活），芯片开始工作，I／OCLK和DATAIN能使DATA OUT不再处于高阻状态。DSP通过I／OCLK引脚提供输入／输出时钟8序列，当由DSP提供的帧同步脉冲到来后，芯片从DATA IN接收4 b通道选择地址，同时从DATAOUT送出的前一次转换的结果，由DSP串行接收。I／OCLK接收DSP送出的输入序列长度为10～16个时钟周期。前4个有效时钟周期，将从DATAIN输入的4 b输入数据装载到输入数据寄存器，选择所需的模拟通道。接下来的6个时钟周期提供模拟输入采样的控制时间。模拟输入的采样在前10个I／O时钟序列后停止。第10个时钟沿（确切的I／O时钟边缘，即上升沿或下降沿，取决于操作的模式选择）将EOC变低，转换开始。

Description: 采用Intel8255端口数据线与上图除IN0~IN7之外的引线连接。
程序步骤：
(1)根据模拟信号输入连线方式(跳线JP10与电位器１相连，若JP10上跳线摘掉，可将电位器２作模拟信号输入)，选择模拟通路，即选定addC,addB,accA组成三位二进制数据；
(2)同时使START和ALE有效，使ADC0809选择相应模拟信号并转换；
(3)等待EOC出现高电平；
(4)使OE为高电平，即允许从ADC0809读出数据

Description: 基带无源EOC的应用说明，是利用了有线电视信号使用54～860MHz高端频率，以太网的基带数据信号使用0～42MHz的低端频率，故两者可以在同一根电缆中传输，结合RF有线电视技术与数据以太网数据传输技术，把以太网的数据基带信号通过合路器馈送到原电视网的分配电缆上，与电视信号一起送至用户。在用户端，通过分离器将电视信号与数据信号分离开来，分别送入各自的终端设备，如电视信号送入电视机，数据信号送入计算机，实现了电视和数据信号在原电视网入户电缆上的合路、传输、分配、分离。-err
