1.1 Flexible Configuration
The F12KDX can be configured as an 8 K by 4 K blocking bi-directional digital switch, a 12 K by 12 K unidirectional
non-blocking digital switch, and as a non-blocking switch with various switching capacities.
A. Blocking Bi-directional Configuration (Typical System Configuration)
8,192-channel x 4,096-channel blocking switching from backplane to local streams
4,096-channel x 8,192-channel blocking switching from local to backplane streams
8,192-channel x 8,192-channel non-blocking switching from backplane input to backplane output streams
4,096-channel x 4,096-channel non-blocking switching from local input to local output streams
B. Unidirectional Configuration
Because the input and output drivers are synchronous, the user can combine input backplane streams and input
local streams or output backplane streams and output local streams to increase the total number of input and
output streams of the switch in a unidirectional configuration.
12,288-channel x 12,288-channel non-blocking switching from input to output streams
C. Non-Blocking Configuration
The F12KDX can be configured as a non-blocking switch if it is an application requirement. For example, it can be
configured as a 6 K by 6 K non-blocking switch:
6,144-channel x 6,144-channel non-blocking switching from "backplane" to "local" streams
6,144-channel x 6,144-channel non-blocking switching from "local" to "backplane" streams
6,144-channel x 6,144-channel non-blocking switching from "backplane" input to "backplane" output
streams
6,144-channel x 6,144-channel non-blocking switching from local input to local output streams

2.0 Functional Description
2.1 Switching Configurations
The device supports five switching configurations. (1) Backplane-to-Local, (2) Local-to-Backplane, (3) Backplane-
to-Backplane, (4) Local-to-Local, and (5) Uni-directional switch. The following sections describe the switching
paths. The switch paths of Configurations (1) to (4) may be operated simultaneously and in all 5 cases the
Backplane streams may be operated at a fixed data-rate of 32.768 Mb/s on 16 input and 16 output streams, or
optionally, at 16.384 Mb/s or lower data-rates on 32 input and 32 output streams. The Local streams (16 input and
16 output) may be operated at 16.384 Mb/s or lower data-rates. When the lower data-rates of 8.192, 4.096, and
