DS16EV5110
Video Equalizer for DVI, HDMI, and CAT5 Cables
General Description
The DS16EV5110 is a 1.65 Gbps multi-channel equalizer op-
timized for video cable extension applications. 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
losses, a common phenomenon when transmitting video on
commercially available high definition video cables.
The inputs and outputs are fully compliant with DVI 1.0 and
HDMI 1.2a requirements and features programmable levels
of input equalization, providing optimal signal boost and re-
ducing inter-symbol interference. The device supports DC-
coupled data paths providing a wider input common-mode
voltage range and eliminating the need for external coupling
capacitors, reducing solution size and cost.
The clock channel is optimized for clock rates of up to 165
MHz and features a signal detect circuit. The loss of signal
threshold is adjustable through a Serial Management Bus
(SMBus) interface to maximize noise immunity.
The DS16EV5110 also provides support for system power
management via output enable controls. Other controls are
provided via the SMBus enabling customization and opti-
mization for specific applications requirements. These include
programmable features such as output amplitude and boost
control as well as system level diagnostics.
