General Description

The MAX3815 cable equalizer automatically provides

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

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.
