Video Equalizer (3D+C) for DVI, HDMI Source/Repeater/
Sink Applications
General 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 ap-
plications 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 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.
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 Repeater.
The DS16EV5110A 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.
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.
