GENERAL DESCRIPTION
The S2080 is a high speed 34 x34 differential
crosspoint switch with both full broadcast and
multicast capability. Any of its 34 differential
LVPECL input signal pairs can be connected to any
or all of its 34 differential CML output signal pairs.
The differential logic data path makes the part ideal
for high-speed applications. The differential 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 S2080 are internally
biased and have internal 100
line-to-line termina-
tions.
LVTTL configuration controls simplify interfacing to
slower speed circuitry. Once a new configuration has
been entered into the configuration register file, the
S2080 can be completely reconfigured by pulsing
the CONFIGN input.
Figure 1 shows a system block diagram incorporat-
ing the S2080 with other AMCC devices. Figure 2
shows the basic operation of the switch.
