General Description
The MAX3815A cable equalizer automatically provides
compensation for DVI™ and HDMI™ v1.3 cables. It
extends the usable cable distance up to 40 meters
(1.65Gbps) and 35 meters (2.25Gbps). The MAX3815A
is designed to equalize signals encoded in the transition-
minimized differential signaling (TMDS
The MAX3815A 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 signal.
The outputs include a disable function. Upon LOS, the
chip is powered down. For direct chip-to-chip communi-
cation, the output drivers can be switched to one-half the
DVI output specification to conserve power and reduce
EMI. The output drive current can also be increased to
allow the use of back termination resistors for improved
signal integrity. Equalization can be automatic or set to
manual control for specific in-cable applications.
The MAX3815A is available in a 7mm x 7mm, 48-pin
TQFP-EP package and operates over a 0°C to +70°C
temperature range.
