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)
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.
