The MAX3805 is designed to provide up to 30in
(0.75m) reach on 6-mil differential FR-4 transmission
line, or up to 24ft (8m) on RG-188A/U type coaxial
cable, for PRBS data from 9.95Gbps to 10.7Gbps. The
MAX3805 adaptive equalizer reduces intersymbol inter-
ference, resulting in 20ps residual jitter after equaliza-
tion. An internal feedback network controls the
equalizer to automatically match frequency-dependent
skin effect and dielectric losses. The MAX3805 pro-
vides LVCMOS-compatible output-enable and signal-
detect functions.
The MAX3805 has separate supply connections for the
internal logic and I/O circuits. This allows the current-
mode logic (CML) input and CML output to be connect-
ed to isolated supplies for independent DC-coupled
interfaces to 1.8V, 2.5V, or 3.3V ICs. The MAX3805
comes in a very small 3mm x 3mm package and con-
sumes only 135mW.
