The MAX3815 cable equalizer automatically provides
compensation for DVI™, HDMI™, DFP, PanelLink
ADC cables. It extends the usable cable distance up to
36 meters. The MAX3815 is designed to equalize sig-
nals encoded in the transition-minimized differential
signaling (TMDS
The MAX3815 features four CML-differential inputs and
outputs (three data and one clock). It provides a loss-
of-signal (LOS) output that indicates loss-of-clock sig-
nal. The outputs include a disable function or the
equalizer can be powered down to conserve power.
For direct chip-to-chip communication, the output dri-
vers can be switched to one-half the DVI output specifi-
cation to conserve power and reduce EMI. Equalization
can be automatic or set to manual control for specific
in-cable applications.
The MAX3815 is available in a 7mm x 7mm, 48-pin
TQFP-EP package and operates over a 0°C to +70°C
temperature range.
