Xicor 数字电位器的基本设计Xicor

简介：Xicor 数字电位器的基本设计

问：如果XDCP是软件可编程，用到什么计算机语言？
答： You can use almost ANY MCU to program XDCP because XDCP is prgrammed through bus signal.
For some XDCP, we do have instuction sets and also programmable by the bus signal

问：Single XDCP与Dual XDCP在结构上有什么主要区别？区别是在可调电阻部分，还是在微控制器部分？
答： Dual XDCP provides seperate supply power to digital and analogue part of the circuitry inside the chip. It has better noise performance but more pin layout...

问：讲解中称 XDCP 的最佳工作点可在出厂前进行设定，请问这种设定是通过半导体工艺进行的吗？
答： For example, you can use XDCP to control the best operting point of you rlaser diode in your product manufacture and testing. What I mean is the application, not for the XDCP because XDCP can work well in all the range specified in our datahsheet

问：Putting Analog on the Bus指的是用Bus信号控制analog信号，还是将analog signal转换后加到Bus上？
答： "Putting Analog on the bus" basically means using the bus to program analog fucntion block in the system (with using XDCP). However, for Xicor, it means more ...

问：可提供的XDCP最大阻值是多少?
答： We provide MAX 100 k ohm end-to-end resistance

问：是否还有其他厂商提供DCP产品？其性能与价格比Xicor的如何
答： Sure that we have competitors but we are one of the pioneers and mostly commits to this market

问：题外话，X1203的内部已有了32.768KHz的晶体振荡器，请部它的精度的稳定性指标是多少，在相关资料中没有找到，谢谢！
答： Well, I try to answer this question inb brief ...
The accuracy of X1203 depends on the accuracy of external crystal. This is one of the reasons why Xicor RTC doesn"t incorporate crystal. We let the customer have the choice depending on their needs

问：What is the usual temperature range of the XDCPs?
答： Xicor DCP has commercial and industrial grade products.
For commercial one, the range is 0 to 70 degress celcius
For industrial grade, it is -40 to +85

问：XDCP的控制器内核是什么？是8051还是RISC？
答： You can either program XDCP usign 8051 or RISC MCU.

问：XDCP可用于输出端做为可调负载吗？
答： Sure that  you can use XDCP in this way. I am very interested in your idea and if possible, please elaborate or you can contact me by e-mail if you don"t like to release now.
