ADV7511 HDMI®发送器支持HDCP 1.1特性;然而,业界对如何正确实现HDCP 1.1的某些特性,特别是增强链路验证(Pj校验),存在一些误解。由于对实现方法存在不同的解释,ADI公司给ADV7511增加了一个HDCP 1.1特性禁用选项。版本ID(主寄存器映射的寄存器0x00) 为0x14的ADV7511器件提供此选项。在以前版本的ADV7511中,如果接收器在其HDCP响应中显示支持HDCP 1.1特性,则ADV7511自动调用此(Pj校验)协议。HDCP 1.1特性禁用选项允许用户通过置位I2C寄存器位来禁用Pj校验。

设计了一种用于高速ADC中的高速高增益的全差分CMOS运算放大器。主运放采用带开关电容共模反馈的折叠式共源共栅结构,利用增益提高和三支路电流基准技术实现一个可用于12~14 bit精度,100 MS/s采样频率的高速流水线(Pipelined)ADC的运放。设计基于SMIC 0.25 μm CMOS工艺,在Cadence环境下对电路进行Spectre仿真。仿真结果表明,在2.5 V单电源电压下驱动2 pF负载时,运放的直流增益可达到124 dB,单位增益带宽720 MHz,转换速率高达885 V/μs,达到0.1%的稳定精度的建立时间只需4 ns,共模抑制比153 dB。

Abstract: Mechanical misalignment and scaling factors lead to a mismatch between the values coming from a touchscreen panel (as translated by a touch screen controller) and the display (typically an LCD) on which the touch screenpanel is mounted. This tutorial discusses how to calibrate the touch screen panel to match the display.

Abstract: A perfect voltage reference produces a stable voltage independent of any external factors. Real-world voltagereferences, of course, are subject to errors caused by many external factors. One causeof these major errors istemperature. Without care, it is easy to operate a voltage reference outside its operating temperature range. Thisapplication note describes how references respond to temperature changes, and how self-heating can cause a voltagereference to operate outside its recommended temperature range. Once understood, this knowledge can then be used toavoid making this design error.
