32 x 32 1.5 GBIT/S DIFFERENTIAL CROSSPOINT SWITCH
S2025
June 24, 1999 / Revision B
EXPANDING TO A 64 X 64 SWITCH
The S2025 includes configurable differential output pair
driver enables that allow it to be expanded to form a 64
x 64 differential crosspoint switch.
As shown in Figure 9, four S2025 devices can be used
to form a 64 x 64 differential crosspoint switch. Each of
the 64 pairs of differential outputs are connected to
output pairs on two different S2025 devices.
Similarly, each of the 64 pairs of differential outputs are
connected to output pairs on two different S2025 de-
vices. The configuration register files of the two devices
are then programmed to enable only one of the two
connected output pairs at once.
With the interconnection scheme shown in Figure 9,
any of the 64 output pairs can be connected to any of the
64 input pairs.
To avoid power-up output pair contention, the Reset
condition for the S2025 assumes a configuration where
all the differential output pairs are disabled.
Normal high-speed PECL routing and termination prac-
tices are required for all PECL connections. For
maximum data throughput, reflected signals from im-
pedance mismatches at the package/pcb boundary, as
well as those due to poor placement of terminating
impedances must be minimized. Care also must be
taken during board layout to position the devices for the
shortest possible trace lengths when connecting differen-
tial outputs together.
Larger differential crosspoint switch structures can also
be built using the S2025’s ability to selectively enable
and disable its differential output pair drivers.
