Description
The DS16EV5110A is a multi-channel equalizer optimized for video cable extension
Source/Repeater/Sink Applications. It operates between 250Mbps and 2.25Gbps with common
applications at 1.65Gbps and 2.25Gbps (per data channel). It contains three Transition-Minimized
Differential Signaling (TMDS) data channels and one clock channel as specified for DVI and HDMI
interfaces. It provides compensation for skin-effect and dielectric losses, a common phenomenon
when transmitting video on commercially available high definition video cables.
The inputs conform to DVI and HDMI requirements and features programmable levels of input
equalization. The programmable levels of equalization provide optimal signal boost and reduces
inter-symbol interference. Eight levels of boost are selectable via a pin interface or by the
optional System Management Bus.
The clock channel is optimized for clock rates of up to 225 MHz and features a signal
detect circuit. To maximize noise immunity, the DS16EV5110A features a signal detector with
programmable thresholds. The threshold is adjustable through a System Management Bus (SMBus)
interface.
The DS16EV5110A may be used in Source Applications, Sink Applications, or as a
The DS16EV5110A also provides support for system power management via output enable
controls. Additional controls are provided via the SMBus enabling customization and optimization
for specific applications requirements. These controls include programmable features such as output
amplitude and boost controls as well as system level diagnostics.
The DS16EV5110A is a pin-for-pin replacement to the DS16EV5110. It features an enhanced
CML output that presents a high impedance when powered down.

在大量生产或销售声称符合HDMI规格的任何授权产品或元件（或让别人做样的活动）之前，每个采纳者必须测试一个代表性样品来进行HDMI一致性测试。首先，采纳者必须按当时的HDMI一致性测试规范进行自行测试。HDMI一致性测试规范提供了一套测试程序，并建立一定的最低要求来指定每个HDMI采纳者应该如何测试授权产品来符合HDMI规格。这种一致性测试只限于用来评估一个产品是否符合HDMI规格，而不是设计来测试任何授权产品的整体性能。
其次，每个采纳者必须提交每个类别（即Source, sink, repeater或线缆）授权产品的第一款产品到HDMI授权测试中心（ATC）进行测试。一旦每个类别的第一款产品通过测试，那此类别的后续产品便不被要求提交到ATC进行测试。例如，一旦采纳者的电视机已通过ATC测试，那其他的电视机或显示器便不被要求提交到ATC进行测试。然而，要帮助确保HDMI的互操作通性，我们鼓励采纳者仍提交到ATC进行测试。
HDMI一致性测试代表授权产品的最低测试标准要求。成功完成一致性测试规格或ATC测试并不保证任何产品都能与符合高清晰度多媒体接口、正常工作或与任何其它产品交互操作。每个采纳者全权负责确保其产品能够正常工作，完全符合HDMI规范和采纳者协议，和能与其它产品相互操作。
