本文介绍了两种分频系数为整数或半整数的可控分频器的设计方法。其中之一可以实现50％的奇数分频。利用VHDL语言编程，并用QUARTERS||4.0进行仿真，用 FPGA 芯片实现。 关键词：半整数，可控分频器，VHDL, FPGA -This article describes two kinds of sub-frequency coefficient is an integer or half-integer divider controllable design method. One of them can achieve 50 of the odd-numbered sub-frequency. The use of VHDL language programming, and QUARTERS | | 4.0 simulation, using FPGA chip. Key words: semi-integer, controllable divider, VHDL, FPGA

TLC549是一种采用8位逐次逼近式工作的A/D转换器。内部包含系统时钟、采样和保持、8位A/D转换器、数据寄存器以及控制逻辑电路。TLC549每25uS重复一次“输入―转换―输出”。器件有两个控制输入：I/O CLOCK和片选（CS）。 内部系统时钟和I/O CLOCK可独立使用。应用电路的设计只需利用I/O时钟启动转换或读出转换结果。当CS为高电平时，DATA OUT处于高阻态且I/O时钟被禁止。 -TLC549 is a used 8-bit successive approximation type of work the A/D converter. Contains the internal system clock, sample and maintain, an 8-bit A/D converter, data register and control logic circuit. TLC549 each repeat 25uS
