Description
The OCX™ family of SRAM-based devices are non-blocking n X n digital crosspoint switches capable of data
rates of 667 Megabits per second per port. The I/O ports are fixed as either input or output ports. The input ports
support flow-through mode only. The output ports are individually programmable to operate in either flow-
through (asynchronous) or registered (synchronous) mode. Each output register may be clocked by a global
clock or a next neighbor clock source.
The patented ActiveArray provides greater density, superior performance, and greater flexibility compared to a
traditional n:1 multiplexer architecture. The OCX devices support various operating modes covering one input to
one output at a time as well as one input to many outputs, plus a special broadcast mode to program one input to
all outputs while maintaining maximum data rates. In all modes data integrity and connections are maintained on
all unchanged data paths.
The RapidConfigure parallel interface allows fast configuration of both the Output Buffers and the switch
matrix. Readback is supported for device test and verification purposes. The OCX160 also supports the industry
standard JTAG (IEEE 1149.1) interface for boundary scan testing. The JTAG interface can also be used to
download configuration data to the device and readback data. A functional block diagram of the OCX160 is
shown in Figure 1.
