GENERAL DESCRIPTION
The S2018 is a high speed 17 x 17 differential cross-
point switch with full broadcast capability. Any of its
17 differential LVPECL input signal pairs can be con-
nected to any or all of its 17 differential CML output
signal pairs.
The differential 10K LVPECL logic data path makes
the part ideal for high-speed applications. The differ-
ential nature of the data path is retained throughout
the crosspoint structure to minimize data distortion
and to handle NRZ data rates up to 3.2 gigabits per
second. The high-speed serial inputs to the S2018
are internally biased and have internal 100
line-to-
line terminations.
LVTTL configuration controls simplify interfacing to
slower speed circuitry. Once a new configuration has
been entered into the configuration register file, the
S2018 can be completely reconfigured by pulsing
the CONFIGN input.
Figure 1 shows a system block diagram incorporat-
ing the S2018 with AMCC serial backplane devices.
Figure 2 shows the basic operation of the switch.
