FHP3350 offers three outputs that can be put into a high
impedance disable state to allow for video multiplexing or
minimize power consumption.
These amplifiers are designed to operate from 5V (±2.5V) to
12V (±6V) supplies. The outputs swing to within 1.3V of either
supply rail to accommodate video signals on a single 5V supply.
The FHP3350 and FHP3450 are designed on a complementary
bipolar process. They provide 210MHz of full power bandwidth
and 1,100V/μs of slew rate at a supply voltage of ±5V. The

Description: Two simple Quadrature decoder and Counter build in a XILINX XC9536 CPLD. This Core is coded in Verilog and contains the compete Project file and the fitted quad.jed File.
The Pinout is descripted in the Constrained file quad.ucf.
To use them, you need teh XC9536 and a clock source that s 4 times faster than the fastes signal that the incremental encoder can creates. IThe clock source frequency is uncritical. For manuel rotated incremental encoder like radio VFO oder other tuning knob, a simple TTL oscillator with about 1Mhz (i use 1.8432Mhz and tested 32768Khz) works brilliant.
For very fast decoding, this core is not good enought because there are no Filter FlipFlops are programmed to suppress noises on the Channel A/B Lines.-Two simple Quadrature decoder and Counter build in a XILINX XC9536 CPLD.

Description: 《数值分析方法库_第三版
》本书选材内容丰富，包括了当代科学计算过程中涉及的大量内容：求特殊函数值、随机数、排序、最优化、快速傅里叶变换、谱分析、小波变换、统计描述和数据建模、偏微分议程数值解、若乾编码算法和任意精度计算等。本书科学性和实用性统一，不仅对每种算法进行了数学分析和比较，而且根据作者经验对算法给出了评论和建议，并在此基础上提供了用C++语言编写的实用程序。
-《Numerical Recipes 3rd Edition: The Art of Scientific Computing》, Do you want easy access to the latest methods in scientific computing? This greatly expanded third edition of Numerical Recipes has it, with wider coverage than ever before, many new, expanded and updated sections, and two completely new chapters. The executable C++ code, now printed in color for easy reading, adopts an object-oriented style particularly suited to scientific applications. Co-authored by four leading scientists from academia and industry, Numerical Recipes starts with basic mathematics and computer science and proceeds to complete, working routines. The whole book is presented in the informal, easy-to-read style that made earlier editions so popular. Highlights of the new material include: a new chapter on classification and inference, Gaussian mixture models, HMMs, hierarchical clustering, and SVMs a new chapter on computational geometry, covering KD trees, quad- and octrees, Delaunay triangulation, and

Description: 随着可编程器件(PLD) 密度和I/O 引脚数量的增加，对小封装和各种封装
形式的需求在不断增长。球栅阵列(BGA) 封装在器件内部进行I/O 互联，
提高了引脚数量和电路板面积比，是比较理想的封装方案。在相同面积
上，典型的BGA 封装互联数量是四方扁平(QFP) 封装的两倍。而且，BGA
焊球要比QFP 引线强度高的多，可靠的封装能够承受更强的冲击。
Altera 为高密度PLD 用户开发了高密度BGA 解决方案。这种新的封装形
式占用的电路板面积不到标准BGA 封装的一半。
本应用笔记旨在帮助您完成Altera 高密度BGA 封装的印刷电路板(PCB)
设计，并讨论：
■ BGA 封装简介
■ PCB 布板术语
■ 高密度BGA 封装PCB 布板-As programmable logic devices (PLDs) increase in density and I/O pins,
the demand for small packages and diverse packaging options continues
to grow. Ball-grid array (BGA) packages are an ideal solution because the
I/O connections are on the interior of the device, improving the ratio
between pin count and board area. Typical BGA packages contain up to
twice as many connections as quad flat pack (QFP) packages for the same
area. Further, BGA solder balls are considerably stronger than QFP leads,
resulting in robust packages that can tolerate rough handling.
Altera has developed high-density BGA solutions for users of
high-density PLDs. These new formats require less than half the board
space of standard BGA packages.
This application note provides guidelines for designing your printed
circuit board (PCB) for Altera’s high-density BGA packages and
discusses:
■ Overview of BGA Packages
■ PCB Layout Terminology
■ PCB Layout for High-Density BGA Packages
