DS16EV5110
Video Equalizer for DVI, HDMI, and Cat5 Cables
General Description
The DS16EV5110 is a 2.25 Gbps multi-channel equalizer op-
timized for video cable extension applications. It contains
three Transition-Minimized Differential Signaling (TMDS) da-
ta channels and one clock channel as commonly found in DVI
and HDMI cables. It provides compensation for skin-effect
and dielectric losses, a common phenomenon when trans-
mitting video on commercially available high definition video
cables.
The inputs and outputs fully support DVI and HDMI require-
ments and features programmable levels of input equaliza-
tion. The programmable levels of equalization provide optimal
signal boost and reduces inter-symbol interference. The de-
vice supports DC-coupled data paths providing a wider input
common-mode voltage range. The wide input common-mode
voltage range eliminates the need for external coupling ca-
pacitors, thereby reducing solution size and cost.
The clock channel is optimized for clock rates of up to 225
MHz and features a signal detect circuit. To maximize noise
immunity, the DS16EV5110 features a programmable loss of
signal threshold. The threshold is adjustable through a Serial
Management Bus (SMBus) interface.
The DS16EV5110 also provides support for system power
management via output enable controls. Additional controls
are provided via the SMBus enabling customization and op-
timization for specific applications requirements. These con-
trols include programmable features such as output ampli-
tude and boost controls as well as system level diagnostics.
