DS16EV5110
Video Equalizer (3D+C) for DVI, HDMI Sink-Side
Applications
General Description
Features
The DS16EV5110 is a multi-channel equalizer optimized for
video cable extension sink-side applications. It operates be-
tween 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 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.
8 levels of equalization settable by 3 pins or through the
SMBus interface

Optimized for operation from 250 Mbps to 2.25 Gbps in
support of UXGA, 480 I/P, 720 I/P, 1080 I, and 1080 P with
8, 10, and 12–bit Color Depth Resolutions

The inputs conform to DVI and HDMI requirements and fea-
tures programmable levels of input equalization. The pro-
grammable 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.
System Management Bus (SMBus) provides control of
boost, output amplitude, enable, and clock channel signal
detect threshold
Low power consumption: 475mW (Typical)

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 signal detector with
programmable thresholds. The threshold is adjustable
through a System 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.
