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 Repeater.
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.
